This is what we look like when we're voiding the warrantee on our new RPM engine by swapping in a performance camshaft. The 'stick is a Hughes Engines grind that takes advantage of the greater rate of lift per degree of cam rotation allowed by Mopar's large- diameter lifter foot. The hydraulic grind is a Hughes HE2430AL spec'd at 0.504/0.515 lift with 1.5:1 rockers. Our stock rockers proved to have 1.38:1-1.43:1 ratios, so true lift was closer to 0.480/0.490. Duration at 0.050 tappet lift is 224/230, and the lobe-separation angle is 110 degrees. We didn't actually coat the cam with lube until final assembly.
