Hey all, I want to build my 350 into a 383 stroker, and i needed help or needed to know what parts i should go with, i.e. crank shaft, cam,heads,pistons, connecting rods, a complete build. the externals i have are slp runners, ported plenum, edelbrock bbk 52mm tb, edelbrock tes ceram coated headers, holley afpr. Any help is greatly appreciated, thanks

 

You could start here.....https://www.thirdgen.org/techbb2/sho...hreadid=276921

 

ah cool, thank you very much

 

Ok well so far this is what I have,
I already have a 4bolt main 350 block to get bored to a 383,

the parts i'm looking at are:

Keith Black Pistons: UEM-kb122030-8
Eagle H-Beam Connecting Rods: ESP6000B3DL19*
CraneCam PowerMax: crn-104224*
----------
I'm not sure what else to go with, i.e the Crankshaft, Rockers, Pushrods, etc, for heads i'm thinking to find a set of used alum heads and have them ported if need be. Any thoughts ? Suggested parts or setups would be great

I havnt desided completely yet weither i'm eventually going with a super charger but i'm leanining towards n/a so i wanna get some high compresion out of this.

 

i think an easier solution for your bottom end would be to go with a pre-balanced rotating assembly. I'm using an Eagle 383 stroker kit for a 1-piece rear seal, but u can get a balanced assembly from almost any manufacturer: Eagle, World Products, Lunati etc... just double check to make sure that you get the right kinda crank for your type of rear main seal. Most of the pre-fabbed setups come with con-rods profiled specifically for stroker applications to minimize the chance of the big end rubbing up on the camshaft.
Even though the eagle stroker kit i'm using has the profiled rods, it still hit the cam in certain spots, so a small base circle cam had to be installed.
The most important thing you can do at this point, is make a plan. Set your goals for this motor as far as how much power u're shooting for, RPM limitations, budget, intended useage etc... and don't fool yourself and get in over your head, be realistic with these goals. once you've established that, you'll better be able to lay out the exact parts to look for. Then u can ensure that you have components that match with each other and work in the range that you want.

 

I agree w/ 1320 Right Ln. ...Plus I see some mismatched stuff internally for your plan. It sound like your combo will make good power, but not enough to justify the use of all forged parts. You were gonna get KB hyper pistons, and H-beams....How much HP do ou want, and you probably won't be spinning the thing much higher than 6,000rpms.....due to the TPI design. Here's what I would do....Buy a Rotating assembly from Scat or Eagle....they havewhat you need, a Cast Steel crank, Forged I beams, and Hyper pistons fro Like under $700...Save weight and money and get I beams...and if it was my engine and I was building it that way, I would probably get a kit like that but upgrade to some lightweight forged pistons w/ it. Also a kit like that is good to over 500hp....are you planning to make more than that?

 

500hp would prolly be where i'd sit, give or take a little more. I see what you mean on the setup i started there, what would be a good rpm range to go with, what other parts should i get ? How much will the SLP Siamere Runner with accel manifold and ported plenum help ?

 

Well, I must say that 500hp w/ the basic TPI setup will be asking alot. Remember TPI's long runner design is for maximum torque, not Horsepower...especially w/ a 383. Your power band will still be low....but w/ a good base manifold, siamesed runners, and ported plenum you should be able to make power to around 6,000rpm's. Maybe alittle higher. Also to make anywhere near that much power your are looking to make, you will need a very good set of heads. AFR or Trick Flow are both good candidates.

 

yeah i've been looking into the trickflows, and i've been thinkin abou those, these right here looked pretty cool that i saw, tfs-30400002**, thats the PN on summit, I'm not all that knowledgable on these build ups, being as this is my first one, i've dropped motors in, pulled them out, but havnt really built one
but i'm trying to find some used ones rather then brand new, just to save some cash. As far as the 500hp, i'm not set minded on that, i'd be happy with around 400 or little over. hehe so i'm not too picky. What kinda of complete 383 setup would you recomend ?

 

Are you hellbent on using TPI? I've heard/read lots of "complications" people have when using TPI w/ 383...mostly with tuning the computer. I would really recommend and aftermarket EFI or a carbureted setup. If you got a set of Vortechs, an RPM manifold and a cam somewhere with 214-220/.480-.500 (maybe a HOT cam or ZZ3 cam) w/ 9.5:1 and topped it with a 650-670cfm I'd bet it would feel like a TPI down low BUT also would pull way more power up-top.

Just my .02

*got curious and ran dyno 2000 syms...*

L31 Vortech (1.94/1.5)
9.5:1
Large-tube headers w/ mufflers
Dual plane manifold
660 cfm carb
ZZ3 cam

400+ lb/ft from 2000 - 5500
453 lb/ft @ 4000
422 hp @ 5500


Same as above but with 660cfm TPI
400+ lb/ft from 2000 - 5000
460 lb/ft @ 4000
403 hp @ 5500

They both have assloads of torque but the carb motor pulls a bit longer, would be easier to tune and MUCH cheaper!

Ok, THATS my .02

 

hmm, thats somthing to think about, i know a guy that has a super ram 383, and he's doing low 12's i belive, but that is also with nos. I would love to go back to carb, but problem is, I dont got a wiring harness for it, and i'd have to get a new manifold, carb. fuel pump i belive(correct me if i'm wrong plz), where is, i already have a custom chip, slp runners, the tpi setup with harness, afpr, bbk 52mm tb. etc. not to metion smog here in cali, not that i care about smog much, i just like to be able to register my car :P. But if you got any ideas on the smog deal that i could do, then by all means i would goto carb

 

Personally I would stick w/ EFI either way....PLus with Cali. emissions you are not gonna be able to pull off using a carb. There are other advantages of EFI also....You decide which you want to use. I have never heard of anybody having problems w/ tuning a 383 w/ TPI....Anybody that has any experience w/ that will know that this is simlpy not true. You could run Vortech heads w/ TPI too. Do some research.....you have alot of decisions to make.

 

well like i said, i wanna stick with my tpi, so i'm looking for your idea for a 383 setup with a tpi no superchager, maybe nos one day. but not anytime soon

 

Having no personal expirience I can't say for sure, but based off of what I have read off of the boards is all i can say.

Yea, being in Cali you may want to stick with an EFI.

In the way of switching to carbs, you don't need a fuel pump, just a return-style fuel regulator.

Wiring harness takes some customization but it isn't all that hard to change from EFI to Carb...if you were really interested I can email you the schematics to adapt your fuel pump, HEI, fans and charging system to Carb.

But again, being in Cali you prolly would have to do a really good job of tuning that carb (can be done though).

Another point...I sold my TPI and bought a carb setup, ended up with 800 extra dollars, and was able to get a nice roller setup for my valvetrain...i guess it boils down to how fast do you want to go/how much do you want to spend-type deal. I would LOVE to get an aftermarket EFI setup...just too expensive for my budget...

 

And what aftermarket EFI setup would that be? Not that I can afford one, but I sure would think that the tuning possibilites of something like the Commander 950 Stealth Ram MPFI would be awesome.

 

lets not hijack this thread from SydwayzTA 86, and rather stick to the question he asked. The carb vs. EFI debate has been covered countless times.

My reccomendation for your built SydwayzTA 86 is the same as 12secformula said, keep things on the less expensive side of the equation, because it seems to me like your going for a high-perf street set-up more so than a strip only engine. Now the TPI intake by design is really going to limit your peak power numbers, regardless of SLP runners or ported manifold. Even if you go with a big, borderline streetable camshaft it's not gonna match to the intake design. So with that in mind, let's shoot for a slightly more realistic goal for peak power if your not going w/boost/N2O... sumthin around 400 ponies.

Don't spend a ridculous amount on heads if u're keeping the TPI, cuz after a certain point the intake simply won't allow the heads to flow to their potential regardless of valve lift. That being said, I'd take a serious look at either vortec heads with a scoggin-dickey TPI base, or something on the cheap side of aluminum aftermarket.

Also, with the long intake runner design, and the increase in displacement... you'll have more than enough torque down low, which allows you to go with a moderately aggressive cam in the range of 218-222 intake duration @ .050". Now, a cam like that isn't the best "match" for the engine, but remember that you'll have quite a surplus of torque at low RPM's anyway.

If it seems like i'm hinting towards goin to a different intake manifold, I am. I thought the TPI would be fine in my car, but after installing a HSR i'll never go back.

 

well heres my thing, i'm thinking about saying screw it, go carb, and every two year drop a pos stock motor in there to pass emmissions. about those schematics, i would love to see those, my email is Walter.Blackburn@advanteck.com did you build a 383 up ? if so what parts did you use, like complete

one thing keeping me from going to carb is, i just bought some brand spankin new edelbrock tes headers, cermic coated, some slp siamese runners, and a holley afpr, :/

 

yeah thats exactly what i want, a high performance street rod, somthing i can take to the strip on occassion, but also somthing driveable. I dont know all the much about the numbers for cams or heads, so if you could please help explain that to me it would help alot, I've looked into the HSR, but only problem there is that it says its not Cali smog legal :/ unless there is one that it legal, then that would be great

 

i dont wanna spend a ton of cash on heads, but i would really like to get a set of alum ones, i just cant bring myself to spend over $1,000 on heads alone though, any thoughts there ?

 

Like I said, you will not pass California emissions if you go w/ a carb, I believe there are laws against that. If you are thinking about going this route, rethink.....do you want to pull the engine every year??....Probably not. Do you want a fun car, that will have strong power and be a blast to drive every day? Then TPI is the setup that you want. If you want to make 500hp and thats why your thinking of not keeping TPI....don't be silly. 350-400 is alot in a street driven car. That is also enough to put you in the mid 12's easy. There is the Super Ram manifold for TPI, that is emissions compliant...just expensive. A good carb, and intake is not cheap either....you have to get quality high performance parts either way. I would rather try to find a way to make a stealthram to work then pull the engine each year.

 

yeah, its every 2 years i would have to smog, and i do want to stay fuel injected, ok so heres where i'm at, i'm going to stay tpi for now, for one cause i dont got $2,000+ for a HSR, and also cause i have alot for the TPI already. So on at note, where do i go from there. I.E which heads, Cam, pistons, (already gettin a set of eagle I-beam 6" rods) so the rods are coverd, so then crank and timing chain would be it

 

It doesn't sound like you need aluminum heads. Just get the Vortecs and keep your compression ratio around 9.0:1 - 9.5:1.

http://www.sdpc2000.com/catalog/3129...-Assembled.htm

*note that you must keep lift small, OR change springs*

With that 65cc chamber, and assuming your block has the factory deck of 9.025, you would want a piston with a 13-18cc dish. That would keep you from 9.2 - 9.65.

For a cam, go somewhere from a ZZ3 - LT4 HOT...prolly closer to the ZZ3 with the Stock-type TPI setup. If you keep the springs stock then the ZZ3 will have too much lift so you may want to look into another cam. Best bet for camshaft is to go with what the cam company recommands.

Oh...and you'd need one of these too:

http://www.sdpc2000.com/catalog/1460...-Baseplate.htm

 

I have a 385, 10.0:1, Ported Sportsman II heads, Flattop Wiseco pistons, 6.0 rods, Scat crank, Hyd roller 218/224 @.050, 279/285 @ .006, .502/.525 lift, topped with RPM airgap and 670 holley. Didn't get to run it last year cause Mr. Transmission said "no". I've run that thing with 350TPI stock, 355TPI built, 355 4bbl built and now 385 4bbl...many cams, many manifolds. That thing pulls like a freakin train...took 30 cubes to make up for bigger cam/carb from TPI with small cam. Now it pulls a lil more than the 350TPI, revs much quicker and pulls harder for longer.

If you keep that TPI stock (no HSR or whatever) then listen to what everyone is saying about "lesser" heads and smaller cams. If you goto a differant injection then by all means get more head (lol) or cam.

 

based on what everyone heres been saying it looks like it would be worth every penny on that HSR, seems if i dont go that rout then i wont get what i want out of the 383, how much are the HSR used usually ?

 

Hey man I think you are confused, HSR is like $550, not $2000 plus. It is a very nice piece. I would run more compression than than, 9-9.75.1....w/ a iron head I would run something like around 10:1, and if you went w/ aluminum I would run like 11-11.5:1.....Scat cast steel crank will run you about $220 shipped, you have rods....Pistons...I would get a quality, lightweight forged piston, especially if you do have hopes of spraying one day. SRP seems to be a favorite, and what I run....they will probably run you like $420. Heads....well for this I can't say for sure, but if you are planning about running a HSR...I am not sure they make one for vortec heads yet....but if they do, they perform very well for what they are. If not those, I would get some Trick Flows...they are very reasonably priced, and they flow very well, and if you ever decide to have them ported, they can be made to flow fantastic numbers. This combo w/ even a small cam, w/ the factory long runner TPI w/ good runners, ported base and plenum would perform very well. Then when you were ready, you could slap that Stealthram on it and it would be even better.

 

i was gettin the price for the HSR in the summit site, do i not need all that ? or is that for somone going to carb that doesnt have efi already ? Geez in which case, i'm sold Holley Stealth Ram for me, lol

 

Yeah, that is for those who don't already have EFI. They sell a maniflod only for TPI. Its very nicely priced.

 

so all i would really need is the manifold, fuel rail and plenum ?

do i use the tpi or the lt1 style tb on the hsr ?

 

aside from the big pieces you already mentioned, you'll need a number of AN fuel fittings, braided hose, whatever adapters, a different water neck and they don't give u hose barbs or plugs for the vaccum accessories.
The TB u already have is the one u use. Oh, n' i forgot to mention in the PM, that my compression is at 9.7:1.

 

what style water neck am i going to need ? not sure what hose barbs are and AN fuell fitting

 

Here's a quick shopping list from CHP magazine that somebody on this forum scanned, not sure who to give credit to but i saved it for reference.
Hose barbs are the fittings that screw into the manifold, and to which you slide vaccum hoses onto. The barb is to keep them from easily sliding off. You'll probably recognize them if u see them, there's a few on the back/passenger side of the TPI manifold.
AN fittings use a special 37 deg. flare compression type fitting to seal. used mainly for stainless braided hose or they can be used for hard lines if u want.

 

ahh ok yes now i know where your talking about, i've worked with my tpi setup so much, swaped from 305 to 350 etc, but i guess i didnt know the exact name for those, hehe, thanks a bunch

 

Check out stealthram.com...it has a list of necessary stuff w/ you do the swap....i believe the total cost for the swap is like $680....or around there. You can also get an idea of what kind of power you can make w/ these manifolds.

 

what would u recomend ? polished or satin ? i know its all visual, but for the cost and time needed to get the satin to look the same what would u recomend ?

 

I would get the polished, especially if you may in some time want it polished. It will take far more time is patience than it is worth to save alittle money...If you don't care whether it is polished or satin, then get satin and save your money. I think they look good either way.

 

what i did was buy the satin version, and polish just the plenum myself. with a days worth of work using a dremel, sand paper and polish, it came out just like the polished version. The base is simply too much work tho... came out very nice if i may say so myself n' it's matches the polished valve covers just right.

 

how good do you think it would look if i just got the satin and power coated it like a Bolt Gun Metal ?

 

It's been awhile since I looked into it, but last I knew, the Holly Stealth Ram was NOT emissions legal. It does not retain the EGR system which is a no-no for aftermarket parts. I may be out of date on this, though (maybe there's some EGR relocation kit or something). Super Ram is emissions legal though. But all the parts must come together right, and the prom will need likely tweaking to get it to pass (especially since you'll need a bit more injector).

 

yeah as far as i know the HSR is not emmisions legal, but it wont take too much work to just slap the tpi back on for the smogging, also as far as i know the super ram isnt all that differant than the tpi, which leaves me in the not to high potential as a HSR

 

I powder coated mine "Almost Chrome." It looked really good for the first month. I think the constant heating-cooling, expansion cycles did in the shiny finish. It started to just look grey after a while, lost all of it's old luster.

 

the hell with powerder coat then lol

 

Well depending how my current project goes, I'll let you know how TPI works out on a 383 in Cali.

My parts just went to the machine shop today, short block should be done in a week, then I just have to gather up some final parts and slap the heads on and put it in.

I am using Edelbrock Runners and a TPIS Big Mouth base, with a ported plenum.

Basically my setup will look like this...

AFR 195 cc Heads, 67cc chambers
SRP Forged Flat top Pistons, 10.5:1 compression
Eagle 5140 Forged SIR I beam rods
Eagle ESP 3.75" Stroke Crank
4 Bolt Roller Block
ARP main bolts
zz9 Camshaft (212/226 .483/.520 lift (1.5 rockers)
1.6 ratio Comp Pro Magnum Roller Rockers
Melling Standard Volume oil pump, with high pressure spring
TPIS Big Mouth Intake Base
Edelbrock Runners
Ported Plenum
LS1 (25lb/hr) injectors
Edelbrock TES Headers, Majorly cleaned up at welds for flow
3" Flowmaster Cat Back
Custom Cold Air Intake
'165 MAF computer, which will be tuned.

We'll see how it all works out.

 

sounds awesome ! cant wait to see the turn out, do you have any pics of your setup ? any ideas when it'll be up and running

 

I have some pictures here and there of parts, but I don't have them on the web yet, I will have to upload some and post them.

The engine will hopefully be done in about a month, depending how things go.
