    108* installed LSA
    3* advanced
    cam was degreed in

    This is in a 3350# 70' Cutlass S post coupe, 461 C. I., reverse valve body/trans. brake Turbo Action 400 W/JW 10" 3400 rpm stall converter, 12 bolt ch**y 4:10 W/steel spool and 30 spline Moser axles, 29.5X10.5X15 MT drag tires M5 compound, fully ported factory "E" heads, Harland Sharp roller rockers 1.6 ratio, 2" Hooker Super Comp. headers, ported EB Torquer intake, 950HP Holley race carb. (4150 flange) and Holley 1" spacer under carb, and an A1000 Aeromotive fuel pump (supports 1200 HP) with 10 AN fittings and stainless lines to carb.

    Default Re: Need specs on Ultradyne/Bullet cam

    My guess would be .017/.019 with a 1.6 rocker arm which I assume you're using? The Ultradyne spec sheet shows .016 with a 1.5 rocker arm.

    Or

    Multiply your rocker arm ratio x .01066 for your lash and add .002 to you exhaust. I got it off the spec sheet for the lobes


    Call Tim as he is the man to deal with!
