I dont intend on doing anything to the leaf springs, perhaps i'll do something with the coil springs up front to handle the sprung weight a little better while I have the iron block in it, Aluminum block should weigh pretty damn close as to what the aluminum big block weighed.
Aluminum weighs 168lbs per cubic foot, cast iron weighs 442lbs per cubic foot... by this math if my solid iron block weighs 430lbs, then my billet aluminum solid block should weigh roughly 163lbs. Cummins crank shaft weighs 125lbs, add the rest of the rotating assembly, front cover, two injection pumps, billet aluminum head and intake, steel exhaust manifold and a GT50, we should be in the ball park of what the power plant we took out weighed total (760lbs).
