408 W2 combo - where to from here

The cam in my motor is [email protected] and .700 lift with 1.6s.
I agree with flyfish a good 8 inch converter is the way to go and that is one of the things I plan on trying.
My car should run better than it does, I just need to make some small changes to get it there. Like shifting at 7000 or so instead of 6500 [motor made peak power at 6600] and also getting the 60 FT time were they should be.
