Can anyone tell me what size Ford engine is in a 1990 Mallard Sprinter Class A 25-SB MH? I am guessing a 454? Should it be fuel injected by that time? Thanks.

If a Ford chassis its would be a 460 V8 and I believe all 460s 1987 and newer have EFI.

454 V8s are a GM engine design.

My 1990 P-30 chassis is a 454. the chassis was built in September of 1989. The motor home was built on it sometime after that. According to the GM parts guy it's a 1989.They listed it as a 1990, it was the last of the carbureted engines. So I guess you will need to find out when the production date was on the chassis.
