I have a 87 Trans AM 350 TPI and I'm wondering if I should install a adjustable FPR. I have ported cast iron stock L98 heads, 24# SVO injectors, 52mm Edelbrock TB, SLP runners, Compcam with 1.6 rockers lift I:480 E:510 duration at .050 I:206 E:210 and soon to have headers and a custom chip. Would it be worth getting one? If so what pressure should I run it at? I'm not sure if I need to run one with the SVO injectors.

Are you kidding? You absolutely need one. Run pressure in the low 40's. Get an autometer gauge that measures rich/lean conditions and youre on your way. It will yield a ton of power too. You'll be surprised.

Does anyone recommend any particular AFPR?

Wow we have almost the same mods... hehe. An AFPR is a must with those mods. I got one, but I can never get it right and it sure as hell doesnt make a SOTP difference that's for sure.
