Get a TH2004R tranny, w/ the BOP pattern. TH700r4 is either SBC or 2.8L patterns. Dump the 301, if you ever take the intake off you'll know why. This is a castration of the pontiac V-8s. Short stroke, no compression ratio worth mentioning, & siamised ports in the heads, if ever GM made a boat anchor this is it. Get a real pont 350, all accessories should swap over, the longer stroke makes much more torque to handle taller gearing. Anotherthing to watch out for on any pont. v8 is very weak timing chain & gears.
