You can do it but wouldnt be worth it imo. Thought about using a converted LT1 intake maybe? Greater gains.

There is an aftermarket Crossfire intake or two out there that look promising, can always port your stock one too.

A couple guys on here have done it with good results. Stock TPI wont do much for you but aftermarket TPI will. I think 383 went with a Superram and maybe QWS did a Holley SR. I may have the wrong user names here but both have been done.

388 Roller with a HSR here. No major changes to the wiring harness. I used the main harness in the 84. I have a 40 some page thread on SV about the change.

DO not waste your money just doing stock TPI.

I went from the x-fire to a carb and then to the SuperRam. Since my harness was pretty much out, I didn't use much of the stock stuff with the Accel gen 6 computer. New fuel pump needed. qws has the ideas you probably are looking for.
