Ok....here we go AGAIN!!! Looking for a 340 CAMSHAFT

Several years ago, I had an all original, numbers matching 72 340 Duster. I rebuilt the 340, standard bore 68-70 pistons, 2.02" valves in the J heads, factory intake and exhaust manifolds and a 650 DP. The cam was a MP hydraulic, either a 274/.480 or 280/.474, maybe the Hemi grind. With 3.55 gears that car was a blast to drive. That cam was borderline for the stock converter and probably would've benefited from something like a Holeshot converter.
