Need more power for your Acura LS/RS/GS (Non VTEC) motor? Crower's line of chilled cast cam cores are not regrinds of stock cores, but semi finished cores specifically designed for Crower that exceed factory specs for hardness and compatibility. These are ground in-house at Crower. No more base circle problems typical with stock regrinds. Crower has developed several performance grinds from stock replacement, high performance street/strip, to full race (drag or road). When using Crower camshafts, always use Crower valvesprings along with some titanium retainers to prevent valve float. Contact us to order.
