90' Chevy 5.7 & 86' Tuned port

[knuckleheaf27]

My question is will a 5.7L Chevy out of a 90' pickup witch had TBI work under a Tuned Port Injection intake system in an 86' IROC-Z witch has a 5.0? I know i may have to work with a few things. I'm just wondering if the hard parts are compatible, like will the TPI manifold bolt up to the heads from the TBI engine? Thanks for any help....

It can be done, but there are a lot more to it then just swapping hard parts. Here is a link for your to read before you get started and you end up with a lawn ornament like most of the guys that used to come to the speed shop to finish the job that end up costing them more since we have to start from basic, by tearing apart everything.

Good luck and your project.
