Ok So I've read the others and am getting confused on some things.

I have a 1986 iroc-z28 with a 305 TPI and a 700r4 tranny. I am/want the machine shop to build me a 350 long block and I want to put a carb on it. So I dont have to mess with any computer crap.

Now with my transmisson work (isn't it electronic so to speak?) and what about my gas sending unit and pump (doesnt it push like 30 -40)

I never done this to this car and a buddy was asking me questions.

Thanks everyone!!!

 

First, I would challenge your assumption that computer functions are crap. That's just wrong-headed, and something you should get over (for many, many reasons).

Now, to the specifics of your questions:

The transmission is only "electronic" with regard to the torque converter lock-up. You need to retain that function. Retaining the computer controls is the easiest way to do that - but if you remove the TPI, you'll have to provide some other means of locking up the TCC. Kits are available, or you can rig up the 4th gear switch on the valve body to have it lock up the TCC.

The TPI fuel pressure regulator controls fuel pressure to the injectors at 48 psi (no vacuum). As the EFI to carb tech article states, a return-style regulator such as the Mallory 4309 can drop that to a carb-friendly 4-6 psi.

As to the 350 long block, beware of what heads the machine shop offers you. There weren't very many good factory 350 heads made, so most machine shops have true "crap". If they try to tell you 882 castings are "2.02's and good performance heads", turn around, walk out, and don't darken their door again.

Not to harp on the point, but unless you're building a car that will have more miles put on it going down the drag strip than any other use, you don't want to go carb. That you are keeping the TH700 pretty much says you shouldn't go carb.

 

I'm running my 700r4 on a 350 carb motor.. have no issues with it what so ever...

 

five7kid,thanks for the info,however I did not say the computer functions were crap. What I said was (I dont have to mess with any computer crap) crap= stuff like i just dont want to mess with changing all the computer stuff around to be able to run the 350 correct,but anyhow. If I knew that I could have a 350 built and use my TPI without a ton of money going into it, it would deff be the way I would go......

 

thanks for the input ronnie.

 

thanks for all the info. With this mallory 4309, is that all i would have to change. Like the sending unit or the internal pump all will be ok? i looked at the mallory but it doesnt give that type of information... Thank you again.
