With GBF forged stroker crankshafts the camshaft lobe hits (with some larger base circle cams) the counterweight on the crankshaft and the cheek alongside the journal. I could simply make the crankshaft smaller, however this would reduce the needed cheek area that controls oil spill off and reduces the percentage of counterweight required by the longer stroke to achieve maximum life. Furthermore, all of the original camshaft profiles were designed with the correct base circle that we made our cranks to clear. Unfortunately, cam grinders stopped grinding to this originally determined base circle size due to the extra expense and time. Even better, Berg cams have far more clearance from the nose of the lobe to the lifter. This practically eliminates the need to cut the case or lifter to attain the correct clearance of 0.040" required. Note: Genuine Engle cams will not normally clear our forged cranks. With our cranks use Berg cams which do not have "-E" after the part number. |
