Engine/ Trans Combo?

aj
why not the kb quench dome pistons if he is running stock heads
256 or 262 lunati Voodoo
or howards 711381-10 255 duration on the intake but 470 lift
or
711651-10
but check the torque curve to make sure there is plenty of "after shift" and low end for that 4 speed with no torque converter multiplication
I think howard must be at .008 would be about the same running duration as 260 voodoo
