413 vs 440??

Find you a 400, drop in a 440 crank and a set of KB stroker pistons for the 451..... gobs of torque and clearance around things will be much better with the low deck motor. Doing this costs about the same as a decent rebuild excluding getting the crank turned down to 383/400 sized mains and getting it balanced. This combo runs better that just about any 440 you can build!!!
