New guy here with a question that i'm having a hard time finding a correct answer for. I Have a 1989 Winnebago 33 foot motor home with a bad trans but a strong 454 and i want to take the engine out and use it in a rat rod pickup. I Keep getting conflicting opinions as to whether i should use it because some claim that the P-30 Truck motor has a longer stroke like a school bus motor and isn't the same as a 454 pickup truck motor. Some people tell me the block is supposed to be different and others tell me the heads are different. Thanks guys.
