the stage 4 camshaft from Rocket Motorsports is a great upgrade for any mid level D series build. Fantastic for hot street cars, largest grind available using OEM core. Offering 11% more intake duration, 6% more intake valve lift, and 6% more exhaust valve duration, and 11.5% more exhaust lift. Very Noticeable power gains when placed against oem Y7 camshaft. Upgraded valve springs ARE REQUIRED
