The kit (P/N 92500035 Black Highlighted, $1,849.95) includes everything needed to make it a 110 and there’s no machining cases or any other Herculean effort required. A set of SE 4-inch bolt-on cylinders filled with forged flat top pistons upping the compression to a spicy 10.2:1 might just be enough to fill your needs, but as the infomercials say, “Wait there’s more!” A lot more actually. A high-lift SE-585 cam combined with high performance springs, and Perfect-Fit pushrods, roller tappets, and new gaskets pumps up the volume to 11. Oh, I almost forgot, included is a heavy duty clutch spring to better handled the added fun power. Yes, fun power as more power is always fun.
