N. novacrazy2007 Discussion starter.This makes the 4.00 stroke crank go into the block about the same as a 3.875 stroke.

Don't confuse this home-grown mutation with the Chevy-built 307 which has a large-diameter cast crank and rods with the 3/8-inch bolts. The drawback to the Chevy-built 307 is its very-low-compression cast pistons.
