I have a 74 Bronco with a pretty much stock 302, and a c4 behind that. The c4 is crapping out on me shift slow, slams into gears, feel it slip when drivin around. My question is should i go ahead and rebuild the c4 or go out and look for a c6? the big differences between them? I'm also rolling 4.87 gears and 35s, also would like to drop a mildly built 351w in it in the next 2 years or so.
