Story: Step-Dad is looking to replace carbs due to one is Edelbrock (non-marine) and one is Rochester Quadrajet Ser# 17059293 (for a 350).
He is not sure whether the engines are 454 or 350.
HE says the serial numbers are 28526 and 27699 (which doesn't look right from the numbers i see on sterndrive.info.
So, where would the serial numbers be so i can look up the block, or.. how can you visibly tell the difference between a 454 and a 350?
Boat: 1979 Uniflight 36ft Sport Sedan.
