I THINK they will. The width of a big block is not that much different I believe and the bellhousing pattern is identical I am certain. Engine mounts may be your biggest trouble but should be locatable. Some others on here may have a better idea as to the comparative width of a BB/SB swap.

BBC is heavier about 150 lbs per engine, and a little wider. Exhaust manifolds will be different. Bellhousing is the same, front or side mounts depending on what you have will be different.
