What Mark at Bullet suggested was a 273-288 @.050 on a 111 lsa. That seams like a lot of duration for only 11.5 comp.
Talked to Cam Motion today. His suggestion was a 272-279 @.050 664-645 lift on a 108 lsa. His theory was to use a tight lsa to keep the pistons cooler. I don't know I guess everyone has there own ideas and theories. I know they both make great cams NA and nitrous.
