ABSTRACT:
Apparatus includes left and right inline type cylinder heads essentially identical to one another and each having an intake side, the left and right cylinder heads being combined into a “V” configuration, so that the two intake sides face one another. A left-head overhead camshaft structure is located in the left head and a right-head overhead camshaft structure is located in the right cylinder head, the overhead camshaft structures being of an end-drive type. A crankshaft is located proximate an apex of the V, the crankshaft having a front-facing end and a rear-facing end, and an offset gear mechanism operates in cooperation with the rear-facing end of the crankshaft for driving the left-head overhead camshaft structure.
