Mine were set at 120lbs closed and I believe the open lift is 270 (maybe a little more). The rocker arms are Clarks "reproduction" rocker arms, which I bought and installed soon after they were first announced (2010-12?). The lifters are "The Source" lifters. The big difference with the cam is the lobe separation angle is way different than any stock cam, and has a LOT more in common with cams made for modern fuel injected engines, and explains the "street friendlyness" despite what its lift would imply.
>     The short synopsis of the fan: approximately 2/3 less power to do a much better job of cooling, particularly under hard loads. It "acts" like the flow has increased quite a bit... Any who have installed it have remarked at the huge volume of air shooting out of the lower shrouds, but the actual flow has not been measured yet. Everyone has reported a remarkable drop in head temps with it, and can really feel the hp reduction, particularly past 3500 engine rpms. Peak shroud pressure with my prototype, with lots of fan air intake modifications was 14.67" h2O at roughly 5500 engine rpm, and with the stock mag fan on my car... it was completely "shot" and presumably into a bad stall at 11.5 to 12.5" h2O. The production fans make my prototype look pretty darned small!! More than happy to answer any other questions about it!! wrokit at hotmail.com
