454 N Code Bloc



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

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?
