Tunnel ram 440

Cam's too big if it's the 680591. There is no 68051 I can find.
However, it should still run.
On the carbs, connect the vacuum pods. Does your carb linkage open the carbs (front and rear, not primary/secondary) 1:1 or is it staged? Also, on the power valves... you need a vacuum gage, and take a reading on manifold vacuum level in gear, at idle. Once you know that number, post it.
