Big block v6 swap

[RebelChevy]

Hey guys, I'm new to the forum! Bing so, I'm not sure this post is even in the right spot but I'll go for it anyways.

I saw a previous thread about a 305 v6 being swapped out for a 305 SBC v8, OP is BigWil. I'm looking into tackling the same project with a 478 big block v6 being removed to put in a 6.5 diesel, but It seems this isn't going to be a bolt in swap. "bigwil" mentioned he was able to fit the new engine right in place with "very minor modification" but never explained how or got any pics posted. So whats the deal? Will the v8 fit in it? And how? What was this minor modification?

AND... I'd love to hear everyone's input on What automatic transmission to sit behind the 6.5 TD in a 35,000 lb bus?

Thanks in advance for fellas!
