Description
This is a new CNC machined billet camshaft core with a new steel adjustable gear. The cam has been precision ground with more lift and duration. The 506 grind is a good governor grind for engines running up to 4500rpm. With peak TQ from 3000-3500 rpm range makes this a good cam for governed tractor pullers, golf cart repowers and mud boat engines. This cam works well with the stock jetting. Customers can expect to see a 3-4hp and 5 ft/lb of torque gain over an out of the box engine.
The camshaft assembly includes the following.
Billet Steel CNC machined gear with hardware $79.95
New CNC machined billet camshaft core $149.95
Grind service, Includes grinding camshaft, hard face overlay lobes, regrind lobes, lobe polish, camshaft ends ground to size, debur and put in an engine and precision degreed in with computer equipment. $300
BUILDER NOTES: It is the engine builder’s responsibility to properly install the camshaft. This includes clearance if needed, checking spring pressure, checking coil bind, using the correct oil, checking camshaft end play and all other engine building procedures. The 508 and 509 camshafts will require valve pockets in the pistons, we recommend a min of .075 of valve to piston clearance.
