HI LIFT CAMS FOR DRAGS AND HI PERFORMANCE
If you are building big engines (96+ cubic inches) or even
highly modified smaller motors and want to run compression ratios of 10.5 or
higher, Andrews Products has new high lift cams available which will put more
usable power at the rear wheel than anything else going. These grinds are
specially designed for highly modified motors!
