    Just to double check, this cam will work with the SD. Not the MAF, and I will not have to get a chip or programmable ECU. What would be the correct lifters to purchase.

    Asked by: non HO 302
    Yes, this cam is optimized for the speed density application. the correct lifters are http://www.jegs.com/i/COMP-Cams/249/832-16/10002/-1
