Question Aluminum BB lighter than SB?
As much as I hate to admit it the SB does seem to rule the road courses.

I have a Ford SVO Aluminum 460 in my car. I am told that the block is in fact slightly heavier than the standard cast iron 460 block. According to my source the Ford Aluminum 460 block was built for strength and not light weight. I have not been able to find the weight of the block. I do not know how the Shelby Aluminum 427 block compares.

I always assumed that something made of Aluminum was going to be lighter than the same piece made of cast iron. Duh, maybe not.

If anyone knows a source for the weights of engine blocks, mine in particular of course, please let me know.
