Finally got a digital camera and snapped a few pics of the 350HO im dropping in the '82 Z, hopefully Thurs-Fri. (but you all know how things go.)

its topped off with an Edelbrock RPM Air-Gap intake, 750Cfm carb, and an HEI distributer.

pics gallore.

It's looking really good. I'm not sure if you did this on purpose or not, but I like what you did what the timing cover bolts and short headbolts. It gives a contrast of color, espcially with a black on block head/block combo. That's my opinion.

sharp looking engine... definately gettin an RPM intake but now i'm thinkin of the air-gap instead. So many choices....

Rubber rockers?

i see RB is a huge fan of the stock SA rockers that come with the crate engines from GM

RB83L69

I don't care if they're SA or not, or new or old, or on a crate motor or one out of a car; they're rubber. No way you can get consistent valve action out of that garbage. I can't see the cam; but even if that motor still has the weenie little thing that GM puts in those still in it, it'll run a whole lot better with 16 rockers that are all the same ratio, and that don't bend 1/16" when they operate.

scottland

yeah... i know the stock stamped steel rollers are pure crap, but if im going to upgrade the rockers, then im gonna upgrade the springs and retainers while im at it, then im gonna have to have the heads machined, then im gonna want a bigger cam. its just more $$$

Also, if im going to spend the money for roller rockers, im not going to buy super cheap ones, and a decent set cots $250+ alone.

As for the cam, yes, its stock, the motor from the valve covers on down is just the way i got it from GM.

one of these days...

for right now the car is a daily driver so i just want to get the new motor in and running. i have a 30min drive each way to ASU every morning, and that would be a long walk

BTW, i had planned to start the swap tomorrow morning, but my buddy that is helping me took next thursday and friday off, not this thursday and friday

So it looks like its getting delayed for another week.

I am running a cam with .487/.490 lift with the stock stamped steel rocker arms that come with the 350HO without a problem.

RB83L69

Look at them with a Strobotach, you'll see a problem. Even a dial-back timing light might show you some interesting things you wouldn't be aware of otherwise.

ive always known that they probably deflect quite a bit under dynamic loads at high speeds and always wanted a good set of full roller steel rockers but the ones for my application are an arm and a leg as far as my budget is concerned.

These are 1.6 ratio rockers. Self aligning. Heavy casting with the added benefit of roller tip. Got mine from Dyno-flow out of Las Vegas for $80.

You're gonna put a holley or a demon on that eventually right?

If that is an Edelbrock 1406, a Speed Demon 650 mechanical secondary carb was worth a full second for me over the 1406 Edelbrock POS. I went from 13.9's to 12.8's just from switching carbs.

Twilightoptics

Edelbrock is good for a few things... reliable, easy to work on..... But they suck in the milage and power programs!

scottland

its a 1407 i believe, whatever the manual choke 750cfm carb is.

here are some updates, anre more pictures. the motor is in, and just about everything is bolted up. Whoever said headers are hard to install is smoking crack, because those went in like cake. quit tonight at like 10:30, just need to hook up some wires, fuel pump to the carb. spark plug wires and timing, fill her with oil and fire it. only problem ( so far) i ran into was a pressure plate bolt broke off in the flywheel at like 6:30pm, so i had to take it down to a machine shop downtown that was still open on a friday after hours to drill the bolt out and tap, but $13.75 later, good as new. i'll post more updates when i get her done. and btw. don't let ANYONE ever tell you that a RPM-air gap intake will fit under a stock hood. LOL cause it will be a cold day in hell before that happens. (maybe if you have an air cleaner base wilth a 3 in drop.)

Twilightoptics

My hedman headers were cake too... until I put the Thicker Decked PRO Topline heads on... then it was a little trickier...

Looks great in there man!

ontogenesis

don't you hate new engines? i thought my car was pretty clean, i thought the engine bay was pretty clean, i stuck a new engine in it, and the whole damn engine bay looked like crap by comparison

speedingpenguin

iTrader: (1)

looks awsome dude...but yeah i'd have cleaned the engine compartment first.....the engine looks so good that just a few minutes with a pressure washer woulda made a big difference...dont know if its too late or not :-D other than that it looks awsome! cant want to be doing that to my car :-P

nichoulasc

looks great man. im thinking about going with the same engine except with a tpi setup.

scottland

alright finally done, after some fuel pump problems, and power steering pump bracket problems, its running. compared to the LG4 the power is unbelievable. the only thing is when i open up the four barrels it stumbles a little bit, then it just takes off. im thinking maybe the stock fuel pump can't supply enough fuel at WOT, there was something wrong with the holley pump i bought, because it just wasn't working, went back to the old pump, and it runs fine, so i don't know. I think i just need to have the carb tuned by someone who knows what they are doing, because i don't think that a 750 is too big.

What trans and rear are you using with this motor?

No its because edelbrock carbs dont have accelerator pumps like a mech secondary speed demon or holley double pumper. When the secondaries are opening there is an additional rush of air coming into your motor, an accelerator pump squirts gas to compensate. Edelbrock has "step up springs", you can buy a kit of them like I did for like $13.00. I can tell you that you will spend a fortune trying to get the carb dialed in like I did...

motor looks awesome, vortec heads are soooooo cool. however, why in G0D's great name did you leave the engine compartment so dirty. i mean, you had the motor out! why not clean it up a bit!

What trans and rear are you using with this motor?

i have a Saginaw 4-speed that came stock in some '82's and the stock rear.

as i soon as i can save the money, im gonna buy a T-56, because no overdrive is killing me on mileage back and forth to ASU everyday. i keep wishing i had a 5th gear to shift into.

i just got lazy while i was swapping the motor, when you run into problems during the swap, the last thing your thinking about is cleaning the engine bay. But i am going to take it and get the engine compartment steam cleaned.

as soon as i get some more money together im going to take the edelbrock carb back, and probably get a demon 650, the edelbrock is just a ****ty performance carb, and i saved my reciept .

its running really well, the power is amazing it pulls like a train, as soon as the motor is broken in, im going to take it down to the track and get some times. (hopefully in about 1-2 weeks).
suprisingly, the air-gap almost clears the stock hood with the air cleaner i have, either a 2" thick air cleaner instead of 3", or a L88 drop base air cleaner, and the RPM air gap will clear the stock hood fine, but im getting an SS hood in a couple of months anyway.

overall though, compared to a stock LG4 with 78,000 miles on it, the 350HO has fullfilled all my hopes and dreams....... for a while atleast

I have a ? about that engine. It says in the catalog, stoggin dickey, that is has a hydraulic cam, not a hydraulic roller. What I want to know is it an early 2 piece rear main seal or the later 1 peace roller block? I was planning on buying that engine....well the long block, and throwing TBI on it with a bit more cam. Thanks for any info.
Lc

scottland

it is a '87 + block. so it does have a 1 pc rear main seal, they simply choose to run a flat tappet cam. the block has provisions for a roller cam, you can run one, if you have the factory style lifter retainer, or you can buy retro fit lifters. keep in mind, that you can't run much more lift, the vavle guides need to be machined, and you need better vavle springs. so watch which cam you run.

if your looking for a brand new motor i would highly reccomend it, it runs great out of the box. im going to the track with it on friday, to pull down some times. so i'll post post them after i come back... this will be my first time at a track, so im probably going to take it easy, shooting for low 14's, my saginaw 4-speed isn't gonna hold up to powershifting very long, so im just gonna take it easy on it.

scottland

btw... about the dirty engine bay... i did a little cleaning last night. while its not perfect, its much better

before


after

305RSlc

Well thanks for the response, and your engine bay looks a ton better. I was gonna run a LT4 hot cam, with new springs of course and some port and polishing to the heads, 3 angle valve job...ya know, the works without blowing too much money. What kind of retro lifters would I need or could I just pull the one off my 305 and use it on that engine since it is a roller cam?( with new lifters of course) Once again, thanks for any replys. And do post some times, I wanna see what this engine is capable of!
Lc

305RSlc

sorry, I meant the lifter retainer off the 305 with new lifters.

scottland

if you have a roller 305, the stock lifter setup will work fine with the 350HO. might want to buy some new lifters, depending on the shape of the ones from the 305.

305RSlc

Excellent....thanks a lot!!! Now I can get the money for it and actually have a "sports car".... I appreciate the help!

lordlexus

Hey, just ran your post with your piks on that engine...SWWWEEEEET!. I recall you saying it was the 350ho straight out of the box from GM..is this right? My question is how much for that. I have to save my nickels. Also, how long to swap it out in total? Could it be done over the weekend? Geesh. That looks sweet. I have a 305 right now and am serioulsly considering it that is for sure. Oh, 1 more thing. I take it you dumped the computer...any problems with that or just unplug it and toss it? Great piks. Thanks
Jay

scottland

Yes the motor is straight from GM, i didn't add up all the money it took, because i would probably be too depressed about it. but if i had to guess.... about $3700-3800 including every last nut, bolt, and quart of oil.
yes the swap can be done over a weekend, just try to get absolutly everything you need before you start. As for the computer, i took it out, and tore out all the associated wiring.

as for track times, it rained here on friday so i wasn't able to make it down to the track, but imgonna try to get some times before the tracks close for the season.

dcm01003

what engine number/package was that? or if u have the part number that would be great too....

That is the 350/330HP Deluxe. You can get it from SDPC2000.com

http://sdpc2000.com/cart.asp?action=...id=120&pid=462

that's the whole engine though. If you wanna do a different intake setup other than carb....get the short block for 2200 bucks and throw whatever you want on there.

dcm01003

great thanks....also, what do you need to do to get rid of the computer and/or egr. I know the distributor needs to be standalone and need a non-egr intake and non-computer controlled carb.

i actually bought the long block version of the motor, so i could run the intake of my choice, i also think it was a bit cheaper in the long run. just make sure to buy a vortec specific manifold, as for a distributer, i just bought one of summits HEI's with a 50,000 volt coil, seems to work pretty well. im thinking about adding an MSD 6A, but theres other crap need to buy for the car first.

as for getting rid of the computer, you named everything needed. you actually can leave your computer in the car, the only reason i tore mine out, is because i replaced my heater core about 2 weeks ago, and it was in the way. it just won't be hooked up to anything.

you'll find that all the wiring related to the ECM goes into the passenger side fender to the outside of the A/C box. you'll be able to rip all of it out.(or atleast i was)

dcm01003

cool...well that seems to be it...just one more thing and i think this topic can die down...do u have the part number for the flexplate that came with the block. I am going to get the base HO model 350 and it says I can use various flexplates/flywheels, but I would prefer just to know which one that you used to just drop it into your car. Thanks again, as always.

my car has a manual tranny, so no flexplate here.

the flexplate you need came from '87-'92 3rd gens w/ a V8.

its a 153 ring gear flexplate for one piece rain main seal crankshafts.
