WebDec 9, 2011 · For example, a commom 208/218-112 looks like this: 208 + 218 = 426 / 4 = 106.5. That's 5.5 degrees less than your lobe separation, so you have 11 degrees of non-overlap. Try again, with a 236/242-110: 236 + 242 = 478 / 4 = 119.5. That's 9.5 degrees more than the lobe separation, so it has 19 degrees of overlap. WebThe aggressive cam allowed the 5.7L to exceed 100-hp per liter or 1.667 hp per cubic inch. Advancing the cam by 4 degrees resulted in peak numbers of 74 hp at the same 6,900 rpm and 466 lb-ft of torque at 6,000 rpm. Advancing the cam improved the output from 4,000 rpm to 6,700 rpm, losing out only the very top of the rev range.
