    I just wanted to post this over here as well for all that don't look in the Jet section. I just put this together its a 496 with all forged internals by eagle 4.25 lightened crank 6.385 H beam rods with L-19 bolts, JE 4.310 forged pistons 10.2-1 compression. AFR 325 heads stock as cast 2.30 intakes and 1.88 exhaust valves.
    Cam is a custom one designed by Chris Straub of Straub technology
    (cstraub69 on the boards) all I will say about the cam is its 689 lift. I have morell solid roller lifters and crain rockers. Victor tr-2 tunnel ram with 2 600's

    I've always felt tunnel rams are underated, especially with good heads. Probably because the carbs don't usually get tuned well and/or incorrect tunnel ram get's used for the application.
    Would be interesting what would happen with larger carbs.
    Have fun with it - sounds like it should be fun.
