The accurate measuring tools in these kits will get you dialed-in for better performance. Each of the Hot Cams kits includes a degree wheel, dial indicator, adjustable magnetic stand, and three positive stops (10mm, 12mm, and 14mm threads), plus a great wooden carrying case to keep everything in. Centerline placement rela- tive to TDC affects how your camshaft will perform and operate. 870819 199.95 METRIC 871698 39.95
