Call Tim @bullet cams and have him use H10 lobes on a 108-110 lsa. I use it on customers cars that want strong street 340-360's that pull from 2500-6500 rpm with mild valve springs(NO STOCK SPRING),120lbs seat-275-300lbs open. I've replaced a few .509 MP cams with this and the results are fantastic. The crosswind intake has worked well and I doubt the ld430 would be an improvement,but testing is the only way to be sure.
