    The engine specs are:
    Bored .030 over
    Stock crank and rods
    Dish Pistons
    World products s/r heads decked to 64cc 2.02int 1.6exh
    Edelbrock Torker 2 intake
    Demon carbs street demon 750cfm carb
    Msd street fire distributor
    Hedman street headers 2.5" true dual exhaust

    Due to lack of funds I am running a stock converter, stock th350, and stock 10 bolt open diff rear with 3.08 gears. Plan on working towards building up the trans and rear soon.

    Your compression May be to low to use this cam, can't see it being much more then 8.5:1 with dished Pistons.

    I put that exact cam in a flat top 350 with 041 heads and went 12.06 with it
    With Canfield heads it can in the 11.30's in the 2850# Race Vega.

    Idled well at 750rpm. Shifted at 6200

    Compression ratio with 12cc dish pistons, 64cc chambers, and .040" quench should be 9.5"1. The Crane catalog says that grind needs 9.5 to 11:1, so that cam should work well.

    Low duration with that lift, should work well with those heads. Not a lazy cam though, run good springs and an oil additive.

    that's a good all around cam grind that can be driven and not max the spring pressure of your heads.

    Pretty sure all the speed pro/elgin/standard cam grinds come from the same factory. I put a speed pro cam in my last 350 and had zero problems. It sounded great and made good power but I knew the rings were gone and I wanted more power. When I pulled the cam the lobes and lifters looked so good I marked the lifters to the lobes and resold it since they were basically still new. I probably put 5000 hard miles on the cam with a lot of 6000 rpm pulls and a lazy break in.

    I can honestly say I have no complaints about it.

    Also, according to the guy who sold me The heads, he had these angle ground which he said bumped it more. Not sure how much though, so that's not much help lol

    I doubt he had the heads milled and if he did it wouldn't be enough to make a difference. Your combo should make good power with that "old school" cam.
