Re: suburban 6.2 diesel to 454 gas?
The motor mounts might not be the same for both engines, but that's not a big problem. Whoever told you it can't fit may be thinking of the diesels GM used to put in cars. They were a Buick-Olds-Pontiac (BOP) engine, so they had a specific bolt pattern for the bellhousing.
I think the diesel cooling system should be good for a 454. You may have to do something with the fuel system though. At the very least, make sure it is all flushed out good. I don't know what differences there were in the fuel system for the diesel.
Its not much info, but hopefully this helps you out.
