what carb would be good on 454. it has a edelbrock preformer 2.o intake internals unknown other than erson roller rockers i have the holley 750 hp off my 40 ford i could try. problem is i still run factory tank and dont want any shit in my good carb. not sure if i can run the carb even on it since other is a spread bore and mine is square. the boat i think is from ohio or somewhere like that it sold one time on e bay cheap it has been repainted red at some time in its life. boat has changed hands 4 times before i ended up with it.
