i want to put a 350 in my 89 camaro rs it currently has the 305 tbi in it, the 350 is out of a 82 chevy van what i was wondering is what it would take to swap these engines and still be able to keep the the computer and the tbi, the tranny s a 700r4 with the 4:11 rear end

I did this swap last year and I am not going to lie to you it was hell , it sounds alot easier than it is . What youll need is a custom burned chip or you can use one out of a cop car caprice with a 350 engine, injectors out of a truck with a 350 tbi or you can just buy a holley 670 cfm throttle body it comes with bigger injectors and flows more thats what I would do ,then you need a 350 knock sensor and esc (electric spark control ) module. You have to do alot of tuning to get it running the way you want but after you do all that it should run good as new. Also you dont really have to do all of that to get it running ,I ran my 350 with everything else stock and it ran fine it just wouldnt idle well . After I could afford everything else I got it.Also I noticed this was your first post welcome to the boards.Good luck.

Irocaholic,

Who burned your chip? Is your engine a roller motor or non roller? I am doing a similar swap. I currently have a 305 roller engine in my car and have a built a 383 non roller motor that I am waiting to put in my car. I was just wondering if you had any advice on the chip?

No one burned a chip for me I just have the stock cop car caprice one in it.(well at least I did back when this thread started almost a year ago). My motor is a roller motor. What is your exact combo on that 383? I didnt need to burn a chip because my motor was basically stock except bolt ons but they dont make a 383 tbi car so your defenetly going to need one burned. Go to www.tbichips.com but if your going with a 383 I would say going carb would be your easiest route. But thats just my opinion.

Hey bro. Thanks for the advice. I talked with brian at tbichips.com and he said he would burn the chip for me.

Thanks

If you do not mod that new motor it is a pointless swap. You will only be gaining a few hp and a lot of headaches. I geuss I am confused because yuor post question states that it is a 93 but then you say it is a 82? Which is it from? The 82 actually makes less power than your LO3 does and the 93 only makes a tad bit more. You will need to burn a new chip for it and you better make sure that the cam it comes with is FI friendly. You will need a 350 KS and ECS module as decribed above.

It may seem pointless but at least you now have a better base to go off of. The sky's the limit with the 350(perhaps not the TBI) but nevertheless it's still a better starting point. I still havent broken into the 14's yet which is kinda pathetic but I'm still in need of some tuning. Tomorrow I get my 3.42's and posi put in so that should help. And my holley tbi came in so all I need now is a good intake manifold and I should be set. In, my opinion I'd still go for it, but if you have the time or resources I would throw a good set of heads and cam in that motor while it's out.

cas0484 I am glad to hear your still chuggin along with your 350 tbi, I am sure with the mods your about to do youll be able to run in the 14's regardless of tuning. Thats with stock heads and cam many L03's dont run that with tons of mods so your looking pretty good man. Good Luck with your new stuff and let us know when you break that 14 sec barrier.

Thanks alot IROC you've helped so much thus far with my swap. I'm anxious to see what the gears and posi do for me. Although lowering my 1/4 is always a goal, it if substantially lowers my 0-60 I'll be more than happy. Since all I do is stoplight to stoplight racing, that's all I really care about. I currently have the holley base and I'm going to use my stock injector pod with my 65pph injectors. When you put the holley on your car which manifold did you go with? I'm looking for the most simplistic one as possible. Possibly considering getting the edelbrock and boring it to 2 inches. However, the pro-jection manifold and good carb intakes are also a viable option but I dont want to do a whole lot of fabbing. What would you suggest? Also, have you g-teched your car for a 0-60? What are you running? Currently I'm only clocking 6.5-6.7 consistently with an occasional fluke(bad start, no traction etc...) around 7.5.

Well I actually dont know exactly what manifold I was running with my holley 670 because I never actually kept it. MY friend let me borrow the holley and an old carb manifold that had the tbi adapter plate on it to do a few runs. Thats when I ran the 14.6 I really dont know what manifold it was it could have been a performence manifold of some kind but it didnt have any markings on it, it didnt even have the firing order on it. I only ran that setup for the weekend until I switched over to a performer RPM intake and a 4bbl throttle body that i modified to work with the stock tbi harness. I then added 1.6 roller rockers. With that setup I was running with Lt1's so the LO5 can be a pretty stout motor once you do a little to it.Oh and no I dont really have any 0-60 times due to the fact that I found my Gtech to be pretty far off. I think it was because of the vibration my loud a$$ exhaust caused inside the car. I ran a 16.0 gtech just before busting out consistant high 14's with the setup in my sig at the track. I am actaully currently rebuilding my motor, I am looking for about 330 hp and 400 tq and sadly I have to go carb now because of my cam choice. I will be sticking around the boards though I plan on starting another RS tbi project with a new car when I get my current one done. Good Luck with the parts. Oh and also I would reccomend going with the performer carb manifold and a 2'' tbi adapter plate if your going with emissions if not go performer RPM.
