suburban 6.2 diesel to 454 gas?

I have a good 1975 454 engine.I am looking to buy a 1986 suburban 2500 4x4 6.2 diesel.The diesel engine is toast.The trans is a 400turbo/205transfer case.

What problems will I have replacing the diesel with a 454?
I was told that the mounting on the diesel/trans will not work with a 454 swap.I can't think of why this would be.

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.
