I have a Proform 750 (mech secondaries) for the 347. AFR 185's on the way. The cam helped make that decision for me (see my last port for cam specs, I got the same cam custom ground with a 110 lobe sep). The GT-40x heads are heading to ebay. Even with the incredible port job, I believe the AFR's will be better.
I sure hope the stock roller block holds together, I'm shooting for 450hp at the flywheel.
Does anyone know if the
oil valley girdle works?
What about the
oil pump, I read somewhere a HV
oil pump puts lots of strain on the distributor gear. Would a standard one work better?
