I didn`t see a gear ratio listed, but considering you have a 4200 lb + curb weight car, a 2.32 low gear toploader, that cam is too big for decent torque at lower RPM, the log exhaust manifolds and puny carb hurt you almost everywhere. If you have stock rear gearing, I would imagine it would be in the 2.75-3.25 range. All this combined with not enough ignition timing and you way below the potential available. If you just want a smooth cruiser, I`d go quite a bit smaller cam in, if you want stronger performance, I`d leave the cam, and change the intake, carb, install headers, and go with at least 3.70 gears, although with that much weight more gear or a wide ratio conversion of the trans would be a big help. Obviously the distributor issue needs to be resolved too.
