What donor car for good EFI? Vortec heads?
hey guys. I have a 98 model 350 in my camaro. THe motor came from a hertz rental truck that was wrecked. The guys before me took all the fuel injection off the motor and installed and edelbrock intake and a holley carb. I need some sort of fuel injection so it will run better, start better, and get better mileage. What kind of car or truck would be the best to steal a system from? I would like to find something that maybe the aftermarket makes a chip for. So I can boost the power a little bit. Thanks guys.

'96-'99 light duty trucks/vans. I think. This is really a TBI question.
Get your own chip burning equipment and you'll be miles ahead of anything the aftermarket could do for you.

oh sorry. I wasnt for sure if it was TBI or if they made any TPI's for vortec heads or what. And since I am doing it as a motor swap, or atleast in a car that was originally v6, I figured I would put it here. Sorry about that.
Was there any cars with the 5.7 that had anything different? What did the impalas and all those have? Would any of that work? Im just trying to see what all would work and what would be my best, and easiest bet.

Well, there are options. However, Vettes and f-bodies were the only ones that got TPI. Everything else was TBI.
Now, what you could do is get a TPI set-up from the bone yard or the classifieds on TGO, and add a Vortec base from Edelbrock/SDPC2000. F-bodies had 350 TPI from '87-'89 in MAF form, and speed density from '90-'92. Which you pick is up to you - MAF is more modification friendly but has flow limits. SD is more tuneable but needs more tuning.

acually ,the vortec trucks had CPI not tbi ,only the 95 and earlier trucks had TBI the CPI system is kinda nice ,i made 265 rwhp in my 97 vortec 350 pickup with just edelbrock headers and a descreened maf i have always wondered how that setup would do in a smaller lighter car

I think I found a good one on ebay. Its from a 98 Tahoe vortec fuel injection. everything is complete. Does this sound like a pretty good unit? It ends tomorrow so I need to know as soon as possible. What is this worth? Also the wiring harness has the tranny hookup. Will it run right with a 700r4? Thats what I have and Im sure the tahoe came with a 4l60e. Thanks guys

i don't know of anyway to hook up a 700r4 to a vortec t/b ,so you will have to run a 4l60e if your try and install the entire injection system ,plus you need a vortec fuel pump ,it requires a little more pressure i think than tpi just google some vortec terms and do some research.

well i must have had the name wrong then ,but yea 95 had the fuel rail spider inside the intake ,i didn't mean TBI when i said CPI and thats when the small blocks went to the Vortec name ,before 95 the engines where TBI lo3's and LO5s and there was something else TBI before then the truck 350's

You cannot run a 700 R4 without the TV cable hooked up that is what controls the line pressure inside the transmission
