I sincerely appriciate all the help......here is a pic of the engines.....the boat is a 91 32 Active Thunder

Check Stem to Stern. The new numbers say it is a 88-92 454 MAG with a bravo.

I was checking 500 bulldog page. If they were bulldog 500 /540 they would have different oil remotes and different engine harness location and came with gil exhaust. Seems more likely they started as 465. Good luck. If they were stroker motors he would probably be telling you that. My 2 cents
