    I think I know someone who has one here in my area, What are you looking to pay for one and I will ask him. I will snap some pictures of it when I go over there on Sat.

    Do you plan on putting this on your car? That big block needing more?

    Well the thing about a VS carb is you can never over carb the engine unless you were to use the white spring (the lightest) same goes for the 3310.

    I put a friends 80531 on the car, just see how it ran, and it was much stronger with that carb as compared to the 750dp that I have on there now. It just likes it better.
    I've got the 4779-2 dialed in pretty well but the bigger carb just runs stronger.
