is there a way to make a Z28 throttle body fit a 3.4, if so how hard is it and would it help any?

thanks

 

It won't help unless you do cam/heads.

 

I don't think the T.B. would match up to a 3.4 intake.????

And I'm pretty sure a 5.7 intake won't work with a 3.4.

 

You have to fab the end of a 5.7 intake plenum to the end of a 3.4 intake plenum.That's the only way I've seen it done.

This is correct. You will have to get someone to custom make the extension to the front of the intake manifold. You can call NuTek, but I think they are around $795.00 and you will probably have to beg him to make it for you. I have one on my car...just got lucky and got one off of a car that someone was about to sell.

Without the custom intake though, the LT1 TB will not fit.
