Sorry, been a bit since Ive been on. Thanks for the welcome! Ended up workin on the vette, it's a 91 that used to be TPI. Converted to carb And vortex heads (did that a while back) and finally updated fuel delivery with 90 Chevy pu fuel pump for TBI. It has a 12 psi output but is identical shape/mount to original vette pump and is quieter than holly pump.
Why bother? Inexpensive to repair over computers and injectors on a 20 YO system.
ultimaley I'd like to drop an L98/350 or 400 xnsmsn and really transfer case into h3. Although small diesel has its merits.
