My 416 has ported W2s and a 273@.050 and .704 solid roller. Its 10:1 and runs and races on 91 octane. Its been 10.61@125.1 @3630lbs just recently. According to Wallace it still falls short of 600HP.

I have fought the 60ft a little recently and I think it can go 10.40s if I get that back and get some better air. It has been 1.411 60ft in the past and my best recently has been 1.48 with some spin.
