Dema Elgin earned his reputation for high performance design and manufacture of camshaft from extensive personal racing history. This full race 306 degree duration camshaft is one of his best developed cams for the Vintage Racer that is looking for the best. The power band for this can clearly depends on compression ratio and intake/exhaust systems but is designed to work best between 4000 and 7500 RPM. It should be used with at least 13:1 compression and dyno tuned to meet your expectations. The intake valves open at 49 degrees BTDC, closes at 91 degrees ABDC, the exhaust opens at 81 degrees ATDC and closes at 49 degrees ATDC. Lobe center on this cam occurs at 106 degrees. With stock ratio rockers the valve list is .427" while with 1.5 ratio the resulting lift is .513". These cams are ground on very special cores that have been cross drilled for improved oil flow and longer life of the cam and followers both!
