I have a 401cid 390 with two 600 1850's on the Ford Al dual plane manifold. The cam is the Ford B cam from the 64 big ford cars. 324 deg. adv., 245 deg. @ 50, Lift is .524. Solid lifter. Too much duration for most but I like it. Engine runs real strong from 3000-6000. However it seems to load up at under 2000 rpm and feels much better when it has its guts rung out.
