Possible Big Block install issue?

I was reading in the engine section that the big block and four speed trucks had a larger hump than the small block auto trucks. If this is the case, will I have any issues going from a 350 powerglide to a 402 th400??

No issues that I'm aware of. My BBC502 and 700r4 fit into my small hump equipped truck with no problems.
