whats the ultimate 350 tbi

[gmcdwight]

I have a 87 350 tbi that i won't to build up.I want lots of low end torque and good horsepower numbers.I also would like a choppy camshaft.Everyone let me know what the ultimate 350 tbi build up would consist of .

go to tbi chips you can find him on ebay hes into making perfomance ships and can give you an idea of what you can do with you tbi but its not like building a plain old carbed engine it take a little fines to make the comp happy

I doubt an EFI engine will like a lumpy camshaft.....you will need a cam that will work with the ECU to make it Happy. Typically, lumpy cams produce lower engine vacuum and more cam overlap which means a bad A/F ratio for O2 sensor. I would build a 383 and keep motor basically stock with bolt ons. You want torque for pulling or for drag racing?

I concur. A 383 Stroker will give you more bang for the buck.  Stroke that 350 out with a 400 crank shaft, balancer and flywheel.

here's a gm crate 383 ho

You can pickup rotating assemblies pretty cheap anymore to build a 383 out of a 350. That is what I plan on doing for my 91 down the road here.

Choppy camshaft and EFI is a bad combination......EFI can not handle low vacuum cams at all, even with a chip.

Not true and are you FAST68?
