84 Berlinetta swap project
So, I hadn't planned on starting this yet, but I am picking up an engine next week and ended up buying some swap components today. eBay is running a promotion for 20% off ANYTHING with code PSPRING20 for today so I took advantage.
Plan so far:
-truck engine
-using 700r4 for now to be upgraded to a t56 at a later date
-tubular k member (I have no fabrication skills)
-learn as I go. First ls swap but I want to jump right in.
So I ordered my LS1 oil pan kit from Jegs ebay store ($206.58) and the Speed Engineering headers from their ebay store ($298) and with the 20% off that was $398 for both. Not bad.
My question now is that I want to buy a K-member today from Hawk's ebay store and I'm having trouble finding the right one, particularly using the ebay store to do so. There are several part numbers listed for the Spohn.
Here is the ebay link to their k-members:
http://stores.ebay.com/Hawks-Third-G...r+82-92+camaro
What's the difference between the 703 and 704? Some are listed as SP-704 or DP-704, what is the meaning of this?
I will be keeping factory A-arms and AC, I believe I can relocate AC but just throwing it out there.
Also, would these be the right motor mounts for the Spohn K-member:

Re: 84 Berlinetta swap project
So I ordered this k member using the ebay code again to get $100 off. Pretty nice.

Should be the right one I think.

Re: 84 Berlinetta swap project
I made another ebay account. A lot easier than I thought it would be, you can link up to 8 accounts to the same PayPal. With the headers and oil pan I added both to cart so it was one order even though it was different sellers it was applied to both items.

Re: 84 Berlinetta swap project
Here's the car this is going in. 1984 Berlinetta 305 auto. 305 is seized up but I'm tearing it down while I get my ls stuff together. Digital dash does work so I'll keep that. I'll also be bolting up to the stock 700r4 because I want to swap to a t56 later but I don't have the money right now. I also plan to upgrade the 4.8 down the road but for now I would like to get it in and running in stock form.
I'm picking up a 4.8 Monday with harness and computer. Planning to try and do wiring myself. Once I get my stock harness out of the camaro I guess I'll get started figuring that out this week.

Re: 84 Berlinetta swap project
Is $450 for a 4.8 with computer and harness a good price? The $350 I was quoted was without the core charge. Didn't mention a core charge until they had pulled the motor for me. It's an 03 with 190k miles. 30 day warranty but I don't know if I'll get it in that soon.

Re: 84 Berlinetta swap project
Got the first piece in today! The ever exciting oil pan
From Jegs. weird, all the pieces were loose in the box, so I had pan bolts falling all over. Found a couple stuck up inside the oil pan after I came up short on the initial count.
I guess I need to get an engine for it now. Should be getting that tomorrow.
And here's some Harbor freight toys I got myself. Can you tell it's my first swap?

Re: 84 Berlinetta swap project
Oil pan looks deep, kind of like some aftermarket version of the truck oil pan. Might hang really low under the car and get smashed.

Re: 84 Berlinetta swap project
Factory pan is right at 6". This is just under 8" at the deepest. Guess it won't work. I wish they'd or dimensions in the listing. Is there a jegs part number I should use? I'd like to be able to do an exchange to pay the difference because I won't be able to use my 20% off again. But my priority is not smashing my oil pan

Re: 84 Berlinetta swap project
I'll return it. I'll get the correct fbody pan when I'm closer to putting the engine in. I have plenty to do before the engine goes in anyway. Learning experience for me to do my research better and pay attention to what I'm buying. I see now in the listing it shows the dimensions of the pan.

make sure to read the stickies here and on LS1tech
Definitely a lot of info to help avoid that type of thing from happening.

Re: 84 Berlinetta swap project
So I have an engine now. 4.8 with 190k miles. It will end up getting rebuilt so I will be doing my research to see what I want to do exactly in that regard. In the meantime I have a 305 to pull and a wiring harness to wire. Also have my speed engineering headers.

Re: 84 Berlinetta swap project
Your options are almost endless. You can stay 4.8, make it a 5.3, 5.7 or even a 383. The key will be figuring out how much power you want to make. That will dictate the type of parts you go with and ultimately your budget. Sometimes it is easiest to do a simple rebuild with a small cam, get it running and go from there.

bare minimum to get going I need my oil pan, motor mounts, and prep my wiring harness. Starter, alternator, power steering are missing too. Also my exhaust. And fuel pump. So quite a bit still.
Since I'm planning to upgrade to a T56 later, I'll plan to do my engine work then too. Also the reason I want to do the wiring myself, so that when I convert to manual I'll already have a good understanding of where my wiring is.

Re: 84 Berlinetta swap project
I’m a fan but f the ‘84 model, and I look forward to reading updates on your project. I did an LS swap on an ‘84 Trans Am. I used a 5.3 engine, and I bought f-body ls1 parts for it (oil pan and accessory drive). Texas Speed and Performance helped me witn my cam choice, and I’m pleased with it. They responded quickly and directly when I emailed them. This website has C100 plug diagram info if you need it:

Re: 84 Berlinetta swap project
So thanks to another spring ebay code for 15% off (pspringtime) max of $50 I ordered the CORRECT oil pan this time from Hawks on ebay. $320 after discount for the kit.
Just need motor mounts now to actually get the engine in the car, and was curious about the clamshells which Hawks sells in pairs for $188 and rock auto has mounts for $72 a piece for the ac Delco, but there's also several options as low as $23 for the clamshells. Is it worth getting the Delco parts or does it make a difference? Does anyone have experience with the cheap ones?

Re: 84 Berlinetta swap project
I have not made much progress. I'm starting to look at wiring and it doesn't look that bad, but I'm also a little scared to start cutting my harnesses up. As far as that goes, should I basically end up with a single harness that plugs into the c100 plug and goes to the engine?
I'm also a little confused with the factory 4.8 harness. If I have the complete c2 connector, why is the easiest thing not to just get the fuse block for it and give it power? Then I would just need to pull a few wires that will go to the c100? is that right? Do I really need to remove all the pins I'm not using from the pcm or can I just leave them?
And what is the harness on the passenger side that comes out the firewall? Where is the pinout for this, does this go to the passenger kick panel?

Re: 84 Berlinetta swap project
Got the heads off the 305 so now I'm trying to get it unseized so I can pull the block. Here's what the drivers side cylinders look like.
If I can't get it unseized to get all the torque converter bolts, how can I pull it from the car? I don't need to pull the whole transmission do I?

Re: 84 Berlinetta swap project
The trans has to come out anyways so might as well pull both. Since you took the top end of the motor off you may want to lift the car and lower the entire drivetrain out of the bottom. You can do it with your basic engine lift.

I have a new k member anyway, so maybe I should just drop it out the bottom.

Re: 84 Berlinetta swap project
I'd have to refresh my memory on auto trans compatibility but it is hard to separate the two while they are in the car. I find it easier to remove the whole drivetrain. If you are installing a new K-Member it can be even more beneficial for you to do it that way.

Re: 84 Berlinetta swap project
Thanks, I'll look into it. If I'm wanting to swap to a t56 down the road, should I really just consider biting the bullet and doing the whole package? Is it a huge hassle to rework the wiring after the fact? I'm kind of thinking I should just get the t56 and rebuild the engine while I have it all out to save me some work, just be a lot longer getting it all together and funded.

Re: 84 Berlinetta swap project
I was tempted once again by a 20% off code on ebay. Got motor mounts, water pump spacer, and alternator/ps bracket to drop the alternator. I didn't want to do a low mount alternator because I wanted to avoid tapping my block. $80 for the mounts from Hawks, $24 for the water pump spacer and $150 for the accessory bracket, both from "lsx innovations" on ebay. Mocked it up on the engine, looks pretty good. Don't have my accessories yet. Ac compressor will stay low mount.

Re: 84 Berlinetta swap project
I haven't gotten the old engine out yet. That's why I haven't got any real progress. Need another set of hands or to get the engine unseized and I've been busy. Spent time looking at the harness though figuring out as much as I can before I start cutting it up.

** There are 2 things that make a 84-86 Berlinetta C100 ( ENGINE harness ) specific to only those cars and unlike any other Thirdgens:
1) There are 2 VSS wires for the electronic speedo sending unit
2) The Window Wiper Assembly Plug/Wiring
Did you cut up your original Engine harness yet ??? If not; I'm pretty sure that I've got a partially hacked Berlinetta C100 engine side connector. If your interested in it send me a PM,... if I hear back from you I'll dig it out for inspection to see what kind of shape it's in. You know what; I think I might still have a spare 4th gen fuse/relay center too....... ?!?
<Edit> P.S. Pull the engine and tranny at the same time. I pull drive-trains solo,.........it's just easier to pull them out together. The front of the engine will need to be very high to make pulling them out as 'smooth' as possible.

I haven't cut up the original harness. I'm still debating how to do the wiring. I watched the youtube videos from the LT1swap.com guy where he rewires the ls harness, and it really doesn't look that bad either. I did get a generic fuse box for free that will hold a few relays and blade fuses so I can use that if I go that route.
You just pull it out the top like that? That definitely seems easier/safer to do solo than the bottom. I'll look into that because the engine is pretty well stuck. Once that comes out I'll be in a good place to start working on the next phase.

Re: 84 Berlinetta swap project
On the Tranny wires,..... how you deal with the tranny VSS wires is gonna' depend on the tranny that you decide to use. The 700R4 in your car now uses a 84-89 electric speedo sending unit. The speedo signals go from the tranny to the Speedo Buffer Box, then out to the ECM, Cruise Control, and Digital Cluster.
If you plan to retain the original digital cluster and use a 700R4 then you're probably all good- at least as far as the speedometer readout. ( I'm not sure if or how the 4.8 PCM speed signal needs to be handled with an auto tranny car. ) I swapped to a T56 using a stock 4th gen speedo sending unit in the tranny and in order to get the digital speedo working properly I removed the stock Speedo Buffer Box and replaced it with a Dakota Digital SG5.

Re: 84 Berlinetta swap project
I do want to keep the digital dash, and for now I plan to keep the 700r4, so that should be easy enough. I'll do some research on the VSS inputs to the 4.8 pcm.
My plan for the future is to go to the T56, so you just used the Dakota Digital box with that? to work with the digital cluster?
Didn't realize the Berlinetta site was yours! I've been referencing that quiet a few times during my research.

Re: 84 Berlinetta swap project
Well I finally got my engine out. Not too exciting of an update for you all but I'm very happy to have finally gotten this done so I can get to the fun part. What I did to free it up was take off the oil pan, lift up the engine tranny up enough to pull the pan out, and unbolt the seized pistons from the crank. From there I was able to get all the torque converter bolts out. I just pulled the block out the top, didn’t even have to remove the hood since I had it torn down to the block anyway.
So while I work on dropping the k member and suspension parts, I've ordered some more toys from rock auto. I got a TYC starter and alternator, never heard of them but they have a lifetime warranty so I'll hold them to that. Also got my engine side motor mounts, and valve cover and intake gaskets and new idler pulley. Still need some more various parts here and there but the list is thinning out. I am leaving the original suspension components for now, I really wanted to go ahead and replace everything but I decided to save my money for swap issues that will probably come up. Maybe in the spring I will replace it all but I am just doing the minimum to get this engine running in the car for now so I can get inspected.
What hardware should I replace vs reuse? I am guessing I should get new flex plate to torque converter bolts, what about the bellhousing bolts? Motor mount bolts? Can I just reuse the long bolts from the sbc or are the different sizes? I have all new hardware for the k member and intake. I’m not disassembling the engine other than the new intake going on and valve covers replace just to check things out up top.

If the bolts are in good shape, just clean them up and reuse them. They aren't torque to yield so you don't have to toss them. Cleaning them well though ensures you get a reliable torque reading when you put them back in.

Re: 84 Berlinetta swap project
I'm going to track all my expenses as well. Here is the google sheets document I will be using. Currently at $3700 including the car. You can see exactly what parts I bought with part numbers, I need to update/add some info but the basics are there now.
https://docs.google.com/spreadsheets...it?usp=sharing
I will be adding a category later for stuff from the car I sell. So far got $35 back in parts (woo hoo)

Re: 84 Berlinetta swap project
I’ve got an exhaust stub broken off in the head. Trying to figure out my best course of action here. Tried drilling out the stud and using a screw extractor, but the extractor broke off in the stud (studception??)
I can’t weld and don’t have a welder. My options are to find a friend, take it somewhere, or buy a new head, either a replacement 862 or upgrade to the 243s or something. I didn’t really want to spend that much though.
Any my tricks for getting it out without a welder and is it worth doing vs just getting a replacement 862 head for $110 on eBay? Or should I just bite bullet and get better heads now, or even a new engine, 5.3 or something?
Easiest option, what if I just ignore the bolt and leave it out of the headers? I mean I'm sure it'll leak but it'll allow me to work out the swap and worry about the heads later.

It's probably a good idea to just take the heads off anyways. Send them to a shop to have the broken stud fixed and have them clean up the valves and replace the valve springs. You can then clean the deck, inspect the pistons and run new head gaskets. This could be a blessing in disguise in the long run.

Think it's worth having work done on the 862 heads or would that money be better spent on getting 799/243s? From what I've read previously might be better off, if I'm at the point of putting any money into the 862s I could just upgrade them. If I upgrade springs now and upgrade heads later I can just swap the springs out, correct?
Think I need to do anything with the bottom end, assuming it all looks good?

Re: 84 Berlinetta swap project
You know, I'm sure you're right. I was looking to cut corners because I'm anxious to get the project done. But I think I've decided, literally just now, that I'll take my time with the engine. I have too much to do and a long winter ahead, so while I have it out I will just stall on putting it in and go ahead and freshen things up. I'd like to do cam/springs together, so I'll do some research on where to go with that.

A ported set of 862 heads will support more power than people think. When you port 243/799 heads and use them on a 4.8/5.3 you often end up with a head that has a too large of a port and you affect the coefficient of discharge. Meaning, you would have a lazy head and lose power under the curve only to gain a few up top. Your engine is small, and those heads can easily support 450hp+ when ported. IMHO, unless you were running a 346 or larger I would keep what you have. There are many shops that have affordable porting services for those heads. Advanced Inductions, TEA, Texas Speed, Frankenstein, Land Speed, etc. Depending on your power goals porting might not even be needed. A valve job, and a bump in compressor goes a long way with these motors. The heads flow around 260cfm stock or so on a 3.9" bore. Talk to your local engine shop. Make sure they have experience with LS stuff and see what they have to offer.

Re: 84 Berlinetta swap project
Will do.
Taking my front struts out today so I can drop the k member and I got one, the other strut stud sheared off 😑
What's the best way to get it out now? Can I just unbolt it from the spindle and pull the assembly out the top?

Re: 84 Berlinetta swap project
Grind a slot in that stud for a screwdriver. Try to get the nut off with a wrench. You might get lucky just hitting the nut with an impact.

Re: 84 Berlinetta swap project
Also got some bolts cleaned up, soaked in degreaser then vinegar (some skipped the degreaser). Soaked overnight and today I scrubbed them. Came out pretty well. They certainly don't look 34 years old. These are the control arm bolts and motor mount bolts.
And another positive note, I got my power steering pump today. My engine didn't come with a ps pump, alternator, or the bracket. The other day I ordered a pump on ebay from LKQ, a company I'd never heard of. Funny enough, I saw an LKQ truck today running around Kentucky. Anyway, I bought that particular one because it showed the pulley with it. Since mine didn't have anything, to buy new I would have to buy a pulley ($20) plus a new pump PLUS core charge since I don't have an old pump. Well, I bought this for $38 assuming it would come with the pulley. Not only did it come with the pulley, it had the bracket and idler pulley as well. It was well worth it, even if this pump with 111k miles doesn't last because it will save me a core charge and get me a pulley.

Re: 84 Berlinetta swap project
I'm debating how much of the engine I want to get into. I guess I am looking at pulling the heads and have them worked over by someone who knows what they're doing. What else should I look at doing before I put the engine in? I really just want it to not blow up, but I wouldn't mind going ahead and getting a cam and springs to match while the heads are getting redone. I don't really want to get into the bottom end too much if I can help it. Would it be a good idea to go ahead and put in a new timing chain while I'm at it? Any other worthwhile upgrades while I have the engine opened up?
What are the cam recommendations for the 4.8?

As for cam, depending on your supporting mods, gearing, driving style, and goals your options are endless. I would assume you want something a little bigger than stock but with overall good drive ability? Since your budget oriented look for a used LS6 cam. If not, be prepared to spend at least $300 for an off the shelf grind.

Re: 84 Berlinetta swap project
I would at the minimum replace the timing chain and lifters. You can buy a set of LS7 lifters for $100. Cheap insurance. I would also put in a trunion kit in the rockers. Other than that, just replace any gasket that you break free.

The only other performance stuff I have plans on for now is what I have, speed engineering headers and ls6 intake, and some sort of exhaust.

Looking at this cam with the ls6 springs, I'm still figuring out cam specs but it SAYS it's just a step above the LS6 cam. Any thoughts?
