The counterweights on the 440 crank will contact the block unless you turn them down or grind the block. Turning the counterweights down is the better method as you loose rotating weight.Makes for quick revving,as do the light pistons with long rods.
451's are a killer combo.They like to rev and have tons of torque.As a real plus you get a factory rod ratio which aids durability and longevity.
