if you "are" going standard trans the ZF s6-40 has a .45 6th which is what is installed in Bella! you find them in 92-6 corvettes!bellhousing is the holy grail, [holley $$ can make you one they have the specs] . Mated to a stroker with 3.23 gives you silverstate speed, I would put a paxton on it for the win unless it bumps you into a class that puts you up against supercars. a diff. cooler might be necessary [not sure about that if only running 100miles]. I believe nascar runs a belt driven pump off the driveshaft but others methods [electric pump} may work!
