4.125 K1 crank is on the way

Talked to my machinest today. My new crank is on the way from K1. I was deciding between 4.25" and 4.125".

With much debate, I choose the smaller crank, 4.125". The torque difference between the cranks is only 10 ft lbs at 6900 rpm.

I will end up with 434" small block.

The couple computer programs we have run, they end up around 660 horse power and 590 ft lbs torque.
