Race Camshaft

Product Information

Based on the Comp XFI lobes, this cam requires a stiff valvespring and will want 10.5:1 compression or higher to really shine.  3500-6500+ powerband, 7000-7500 Peak.  Idle will be lopey, but still streetable, especially with the recommended compression ratio. If you run this with stock compression, the lope will be more pronounced and idle vacuum will be effected. 

Custom length pushrods, PAC 1518 valve springs with spring pocket machining,  LS1 seats, and matching valve stem seals for your guides are required.  Seals are basd on either .520" OD or .533" OD depending on the year of your cylinder heads. Stock blue seals are for .533, orange are .520.
