Got the R&D Stage 1 cam into Big Bird, my '88 tan F-250. This motor currently has a stock '88 bottom end that was evidently rebuilt around the year 2000, heads that Typ4 clearanced for me, the R&D cam, exhaust piping from a Banks Sidewinder kit(crossover pipe was copied and built by R&D after the original broke), a lowest-bidder Ebay intake piping kit, and the most important part, my S360 turbo with .63 exhuast housing.
The great part of it is that it's definitely got some power, and under deceleration it's nice and smooth - no ticking/clattering. So the valves and pistons have good clearance and everything's working right.
Currently, it needs a little advance up high - I'm guessing the better flow characteristics of the new cam are probably reducing intake temps due to less restriction. I also am seeing a little less boost from the turbo, but still... I've gotten it up to 24 PSI unloaded in 4th.
