needs some insight
 

just got a bad ass jet boat with an 455 olds engine number 396021f cant wait to get it on the lake! but (there's always a but) i need a flywheel to turn it over! i am not sure what car this engine is from or what cars would be compatible all i know is its from a 68-72 Oldsmobile any insight would be greatly appreciated on where and how to find this part.

check ebay... you're lucky that 455 flywheels are all the same between 1968 and 1990 if you have an auto that is.... don't pay more than $150(new) $75(used).
