Yes we decided to go with the longer crank to provide a larger sweet spot for torque. The 66 gives a relatively short and high rev band, which is cool, but you have to keep it in that sweet spot or you are bogged down. Anything below 5k you are cooked. This is just as it applies to race engines thiugh of course.
Will move the powerband to the left with the longer crank. It did require me to have custom ps and cs made though. Would have been easier with the 66.
I hear ya...
not much torque from my motor.
with the 66 crank, and 5.5 inch clutch..
its even tough to get rolling in the pits with the "F" gear in 1st position
we ended up with a pretty special trans and gearing to make sure its always in the powerband.
