Searching for a factory 340 1970 camshaft!!!

I put one in my 71 4 speed 340 Duster. It was respectable, but I wished I had left the factory cam in. The 268 felt like had a little more torque, but gave up more at the top end. I ended up putting a TRW 284 duration solid cam from the 273 in the 340 and the stock 340 cam in the 273 and they both ran better. It's the combination in the end.
no argument here. Because it was a column shift automatic, I just left it in Drive. It shifted when the governor in the transmission said to. I wonder what happened to that car. He sold it about a year or two later. It was FK5, deep burnt orange metallic, with a maroon velvet bench seat.
