Hello all, I just purchased a pretty sweet 72 Challenger. I got it for a steal. Problem I have is the previous owner could only tell me that the guy he bought it from said he put a crate motor in it. Didn't know what size or anything. I am not a knowledgable Mopar man. I have the engine casting numbers but can not find anything on it. Here they are; drivers side #53020008360 Passenger side is 13089 at clock symbol. I am pleading for help, not knowing is killing me. The motor is killer and sounds phenominal.

based on the one number My guess would be a 360 motor. Hopefully they put a 360 HP 360 ci Mopar performance motor in it for you...
