All I know it is a 2332cc aircooled engine with 145hp
84 mm stroker cam and 94 mm pistons and cylinders. Good size engine and 145 hp is probably right.
As @edsnova said, it's a type 1 engine. With the dual Kadrons (with bigger venturis), I'm guessing a camshaft/rocker combo that goes to 5,000 (or a touch more) rpm with power and lifts the valves to over .450", Los Panchitos cnc'd heads, 8½:1 cr and 1½" exhaust. It'd be a stump puller from about 1500 rpm and up. I think the Kadrons would be just about at their limit, and I'd also guess that even with the longer 3.88 r&p it would be surprisingly quick off the line... Al
