    My buddy is putting a 454BB in his 85 chevy truck. My truck could be his truck's twin, they are identical same color and everything.
    The motor came out of a vaga wagon drag car. It ran 6.40 in the 8th mile.
    He's taken a lot of the timing out so he can run pump gas, But' he did install 3.73 and a posi.
    Do ya'll think I'll be able to take him w/ the set up I have now. I don't think he will be abel to hook.

    I may be doing the turbo kit sooner then I wanted.LOL
    SOON TO COME!!!!

    As you currently sit you'll be fortunate to break into the very high 8s.

    No faith.
    Should I do the "well at least my truck gets good gas mileage" when he hand's it to me?

    What do you think his truck will run? He's probably 2000lb more than that vaga. He won't hook and launch like that vaga. Plus less power from taking the timing out.
    And went from 3in exh. on the vaga down to 2.25 on his truck.

    I would guess mid to low 8s until he gets the rear end to hook up. A posi and caltracs should get him into the high 7s.

    You better lube up, LOL, jk.

    He's probably pushing close to 500hp at the engine and all that torque will get that heavy truck up and running.

    If it was a stock 454, like in the 454SS trucks, you'd beat him, but once you start moddin those BB watch out.


    good luck and have him give you a head start,

    I have a feeling that any BB engine that ran a 6.40 in the 1/8 isn't going to run out of top end. It may run out of gears but I bet that engine will pull hard to about 8,000 RPM.
