    big block tunnel ram in jet boat, need carb help

    I bought a jet boat with edelbrock street tunnel ram and 2 1850/ I guess 600 cfm carbs, vacuum secondary with side hung floats. they are old and leaking, I want to replace them but I was told by jegs to use 2 double pump carbs with center hung floats. I am concerned about washing cylinders. has comp cam 568/ 578 lift and 292/296 duration, give me some advice, thanks

    I have read vacuum secondary on a tunnel ram won't work right due to low vacuum. Contact Holley or Quick Fuel or some other carb manufacturer and see what they say.

    My old boat had twin 850's on it, and I didn't have any issues, other than keeping fuel in the tank...
    If you think nobody cares, try missing a payment...
