8 3/4 gears

Nowhere did I say what the op needs as I have no clue, as a matter of fact I said to make sure he discusses that with his cam guy (we agree on that but I think he needs to stick with Jim), you are the one telling him what he doesn't need. I simply said 256 @.050 is not a very big cam for a stroked small block that's being street driven. Your duster is the only thing that even remotely relates to the discussion here so unless you have had your hands in building multiple small block mopars in different configurations and drove/tuned/rode in them what other experience has any relevance?, snowmobiling? :D
Did I say what the op needs?..
Usually I just give people my experience with the stuff that I've done...
I know in the 65 GTO with the torque of the 400 and the freeway gears it had taking out the Muncie and putting in the tkx 5-speed in it sure helped both ends... It's definitely just a driver with no drag strip intentions..
Aka .. a better combination for the intention...
