The "Hi Boy" motor owned by Don Monaco and built by Yosemite Machine, Modesto CA
El Mirage and Bonneville Land Speed Record holder. 175+ MPH in a roadster on gasoline! Features a set of modified Sharp heads and a Wilcap 8BA-350 adapter. Congratulations to Don, Joe, Terry and the whole crew.
These are the Cylinder Heads & Manifolds that made 10% MORE POWER than any other brand ever tested by Tony Capanna himself on the Indy winning world famous Wilcap Dynamometer. And they look great too! Designed and until recently manufactured by Flathead and drag racing legend AL Sharp! All Sharp heads still incorporate support and directional flow ribs over each dome as well as flow below the bottom row of studs and additional material over the combustion chambers allows up to .375" pop-up domed pistons.
Heads are machined to your specifications to match your engine. Combustion chamber volumes from 53 to 80c.c.s, valve pockets from stock to + .500". All heads come with a spec. sheet showing exactly what compression ratio will be obtained when used on a particular displacement engine. Special compression ratios, valve clearences, domes, etc. cut on request.


Let the other talk about what their heads could/would/should do. When the flag drops, the talking stops.
