Don't forget that ALOT of the parts you need you can get from FLAPS and save a ton of money.
I have a 55 car 235 engine in my 52 so when I order parts for that I just tell them it's a 55 Bel Air with a 235 so it's all good .
But gaskets and that stuff get from FLAPS plus if it is wrong it's only a trip down the street.
