i've got a '63 imperial 413 motor i am going to rebuild hopefully just a re-ring. it will go into my fed. i am aware that the bottom end is the same as the 440 but what i would like to know is why is a rebuild kit so much more for the 413. if everything except the pistons is the same why so much? i guess what i am getting at is, can i just buy a kit with bearings and gaskets for the 440 and get rings for a 413? i have race heads and cam for it too. i also have a complete 440 but a cast crank type. nhra will not allow them to race because sfi balancers are not made for them. please don't go off on a tangent about rebuilding the 440 with all new rotating assembly because i am not as well heeled as you all are. that's why i drive a dragster. they go a lot faster than a door car for a lot less money.
