454 carb to 525 EFI Conversion
 

The 4 454 400's in my Cary are getting long in the tooth and I'm going to have to do something after next season. Actually, I should be doing something this winter but that would be stupid... So the question I have is this:

Should I be watching the classified ads and pick up 4 525's for a great price or pay retail to have my 4 slugs rebuilt? I suspect the 525's use a different wiring harness and a lot of other electronic stuff that is not currently on my 454's. So it could be that someone could give me 4 525's and it still cost me more than rebuilding my own motors in rigging costs.

Specifics: 4 454 400hp, Quadrajet Carb, Velvet Drive, TRS

Ideas?

Have you thought about 496HO's???? If you buy used 525's, you would probably be looking at valve jobs and headers in a few years.
