Alright so my lunati timing set has play in it again. Im not upgrading my opti n crap cause my msd opti is basically brand new and i cut my cam pin down already. Ive though off machineing down an old cam sprocket with the spline to just the cam bolt holes and spline. Then jd bolt it either behind new timing set with a crank spacer or in front pf new timing set. If i do that then pretty much i can use watever timing i want. Ive though of going gear drive just because there hard to destroy. I know it would make my knock moduale crazy so i would just tune out my knock sensor. I figure a carberated engine has no knock sensor so if my tune was dead nuts then i wouldnt need it no?
