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.
