A hydraulic roller camshaft from COMP Cams, part 11-450-8, is engineered for hot street machines requiring 2,500-plus stall and 9.5:1-plus compression ratios, with best results using headers and aluminum intake manifolds. This Magnum series grind operates from 2,500 to 6,200 rpm and delivers 0.578-inch intake and exhaust valve lift with a 110-degree lobe separation angle. The 290HR grind is manufactured from austempered ductile iron with a 3-bolt gear attachment and requires valve springs for installation; lifters and assembly lubricant are not included. Important: BBC models from 1965-66 with 396 c.i. displacement and an oiling groove in the rear journal will not accept this camshaft; if such fitment is required, please contact customer support.
