    Valve Train Time!

     



    Ok folks! it's time to start piecing together my valve train for the 377 that's going into the el camino. I want to run this thing on the street with maybe 5-7 passes a month at the drag strip. However, I do want to build it pretty radical. This is a "toy", a "friday night special", "pro street" I guess you could call it.
    Here's the info I can give you:
    th350 trans,
    3.73 posi rear,
    377 cui SBC: forged rods/pistons, cast steel crank, balanced.
    I'm going to run a vacuum can so a cam that produces good vacuum isn't necessary. I'm going to use my 441 castings which I will grind minimally to try to keep that huge combustion chamber in order to keep this beast on 93 octane.
    How I set up the heads is going to depend on what camshaft I end up with.
    I'd like to be somewhere in the neighborhood of .600" on the int and ex. Maybe I'm steering in the wrong direction in wanting to run pumpgas with that much lift but if you don't know something, you have to learn it so that you know next time. My request is, if anyone could show me some light on where to find a cam of this magnitude. I have already located a pair of Pro Magnum steel roller rockers for 232 dollars. so thats taken car of but the lifters/valves/springs/cam are still open for debate. As far as stall goes, I'd kind of like to be in the neighborhood of 2500-6500 for operating range. maybe 3,000-7,000 if needed.

    And on a last note, I MAY run nitrous with this car at some point, not really sure yet.
