clifford is still around i just got one in the mail yesterday. about 200 for just the cam, 350 for the complete kit. that's for a mild performance cam. thay say you have to have the hardened push rods and tougher springs for it so i got the kit. the delta place might be just as good and a little cheaper. no matter which one i got i would put it on v blocks and check for for droop. i was on the 3rd one before i got one within specs from my local parts store for the 250 i built last year. lots of places store them on their sides.
