G50 Engine swap

[CoffeeMonster]

Hi!

How to make a long story short?

As a former mechanic now truck driver, I was given an 1990 Empress class A RV on a G50 frame with a 454 carburated Chevy engine. Every thing runs fine but it has serious body issues. My wife and I gave long thoughts about rebuilding it but we found a 1992 with a great body but a seized engine. That one also on a G50 but with a TBI454.

I found that to convert the TBI chassis to a carb, it would require a lot of changes even if I have most parts off the old RV. On the other hand, if I can only change the block, it would allow me to do much less modifications.

I am wondering, before pulling out the engines, if both engine block are compatible.

That way I may only have to swap the intakes and the exhausts manifolds instead of the trannies, the distributors, fuel pumps, etc, etc

Any tips welcome!
