    Default New to Jet Boating, Questions

    Greg,
    Just bought my first jet at 52 years old. Its a 1978 Condor Sprint with a 454. motor was just redone bored 30 over with a summit cam...paper says .50 lift with238/248 duration, says advertised as 0.540 lift with296/306 duration. Looks like it has stock intake. the carb is a holley 750 Dbl Pmpr. carb looks bad has broken overflow spout. My question, going to buy new carb and maybe intake. Does it need a Dbl Pmpr ? Which carb and intake combination will work Best?

    My first post,too long?
    Thanks for any imput

    Being it has taken you 52 years to buy a jetboat lets see if we can't make it a enjoyable experience. Have you removed the intake manifold to see if it is a retangular port head or an oval port cylinder head this will make a difference when you select an intake manifold. What exhaust are you running on the boat?What inginition do you have? Once we have this info I will be able to help you with your selection.

    No ,I havent removed anything, Just got the Boat 2 days ago, been checking everything out. Boat has Basset water injected headers. AC/Delco distributor, looks like one off any OLD chevy engine. The intake is an aluminum GM #12363403, the internet said it was made for GM by Edelbrock. Dont remember if it said anything about the ports.

    Couldnt find any name or identifaction on pump. Found the guy who owned it before the man i bought it from. He said it was a Dominator. Good/Bad ?
    Also, do you know of any jet pump shops in Texas?
