Torque converter question......am I crazy?

Not sure what the LSA on the cam is. It is an old Engle piece, HE 3844BL. Anyone know where I can get a cam card? And yes, I advanced the cam 4 degrees. The car was respectable around town last year......I will see what options come up but will likely end up trying the converter. Wouldnt a dual plane be better with the heavy car, or does the gear ratio and loose converter make up for it?
