I did read all of tech inspectors article of braking a camshaft in and still failed me but I like the point that yes the motor ran great it exceded my expectations, and I think what coulda been a culprit was the factory non adjustable rocker shaft maybe, and the numbers look good on that howards cam, and the real problem is budget with converting to roller cams but i said I'm gonna do it right this time though so I'm gonna do the roller cam this time
