How well will a C4 tranny with stall converter and shift kit hold up to the power of a 351W? I am getting a 351W for my 66 now because the 302 has some kind of internal problem and blowing tons of oil out of the dip stick and pushing the dipstick out and a few other things. The 351W will have a decent cam for street/strip, good ignition system, Air Gap Edelbrock manifold and 650cfm Holley or Speed Demon too.
Last question, how hard is it to get about 350 HP or 400 from a 351W? Would it take heaps of work or is that a reasonable goal? I'd be happy with 350 but if 400 isn't hard to get out of it then I will be happy with that. I want to give my 66 a pro street look but I just wont have the big block motor to make it run but it's my everyday driver so you get the drill.
This little 302 did fine in the heavy truck but just doesn't have any torque to get it going, I am hoping the 351W will have a little more at least.
Thanks for any help guys!
