Howdy all,
My 454 went to the machine shop today for a block dip, new bearings, and valve jobs on the heads.
I’m adding in this Howard’s hydraulic roller cam and lifters, matching springs, headers, rpm air gap intake, Holley sniper, 2.5” x pipe exhaust. My question is should I do new pistons as well? This cam is geared for 1400-4900 rpm.
