Both engines have been pulled out, the main differance noticed is the timing chain cover and oil pan. Is there a replacement timing chain cover for the W code engine that can receive the crank sensor?

Can a 454 W engine code bloc be used to replace a N code bloc? I have a seized up 454 N TBI engine and a good running 454 W 4bbl. I just want to swap blocs and keep the TBI running. It's in an early 90's motorhome and it's just to keep it running around THanks all

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! Jean
