Yes, the 250 has the same bell housing bolt pattern as the V8's.
I'm not the one to give advise on installing side motor mounts (V8 style) and leaving the bell housing as well...Chevrolet never did it that way, they kept the front mounts with the bell housing mounts. maybe someone else can jump in and advise it that's the correct way to do it or not.
With that said, the V8 swap would be way easier than the 250 swap...the V8 is 100% bolt in using factory provided holes!
