BIG BLOCKS AND CYLINDER SLEEVES


APE is recognized as the leading manufacturer of big block cylinder assemblies for over twenty years. Our blocks are the strongest and fastest you can buy.

APE big blocks have held the drag racing top fuel records for over ten years. That currently stands at 5.89 sec e.t. at over 243 mph by Larry "Spiderman" McBride. The same blocks we build for the world' s fastest racers are also available for your race bike or street hot rod

The Kawasaki blocks are available in two types. The "KZ style" ( rectangular cam chain tensioner hole) and the "GPZ" style ( round cam chain tensioner hole)

NOTE: BIG BLOCKS NO LONGER HAVE "APE" CAST IN THE SIDE.

APE blocks are only available with piston purchase from APE.

Completely finished, ready to install. Bored, honed, o'ring (if necessary.)
