I am thinking of finding a late model 350 and stroking it to 383 cubes but i want to keep my tbi system. i would probably go with a performer intake and a new chip. but here is my question has anybody had any experience with the aftermarket throttle body that holley make i believe it flows 670 cfm , but i think it is made for pickup trucks just wondering if anybody out there has ever used one before. I dont really want to go with tpi because it has been done to death.. just wanting to do something diffrent

 

The TBI system itself isn't a resriction like most think. It is the heads, and cam. All TBI stuff is interchangeable since the LO3 was never really a " F-Body " engine.

Quite a few people have simply upgraded to a 350 TB or a 454 TB but I have heard good things about the Holley stuff too.
