I need to chime in, what would give me the biggest gain from a 6262 jb? Looking to go bigger and go w bb if it's going to be a noticeable difference. Looking at hartline performance - 6466, 6766, 67HPQ or 71HPQ? Running a Carrillo forged stroker rotating assembly, ported iron heads, ported manifold, roller valvetrain w sharp rockers and 214/214cam all built by Dan Strezo at DLS. Trans was built by jimmy and its his strongest 200R4 he can build w billet input/output shafts. Had him also install billet yoke and trans brake. Torque converter custom built by dusty Bradford PTC3300 non lock up. Running 80# injectors w racetronix dual pumps and Razor Alky kit.
