Bruce will be testing several camshafts, and he shared the smallest and largest cam dimensions with us to show readers the range he's looking at. None of these dimensions are final, of course, but this is as much camshaft info as we could share at this point in time. Kent has several Comp Cams in tow, with the smallest checking in at .617/.607-inch lift (intake/exhaust), with 248/252 degrees of duration at .050-inch lift and 114-degree lobe separation. The largest cam he's planning on measures out at .634/.607-inch lift, with 258/262 degrees of duration at .050-inch of lift and 112-degrees of lobe separation. The lifters are standard Comp Cams High Tech Lite (HTL) solid flat tappets, carrying PN 807-16 and maintaining Buick's factory lifter diameter of .842-inch.
