60401 is the 256/262 dur. cam, 60402 is one step up at 262/268. Both are voodoos... Go to Lunatipower.com and look at their lineup.

sorry to sound ignorant but what do the durations do for my set up? More duration requires a motor with higher compression right? Im leaning more towards the 01 for my little 318
