Has anyone had any experience with the 93-3031-k clifford cam? I think it might be the wrong cam for my set up as im not getting any low end power. it either pings if i run the timing up or spits though the intake if i retard it. The only specs clifford provide are 270 .214@.05 .478 lift. Ive tried richer jetting as well and the plugs are reading like its running fine. The motor is a 66 200 with the block zero decked and 60 thousands cut off the head. It has oversize valves in it as well. Also the head has been modified to accept a 2 barrel weber 38. I put a compression guage on it and it almost read 120 psi cranking with all the plugs out and floored. Any ideas? This is all on 92 octane
