273 Rocker on 340

I have a set on a 340 and they work fine. No grinding. Small cam/springs.

I also have a set of Comp Cams Magnum rockers (not 5.9/5.2 Magnum) on a 318. They were $600 more than the 273’s.

That’s a good looking cam. I have always liked my cams in that neighborhood. My 73 Duster has a 222 @.050, my D100 has a 226, and 70 ‘cuda has a 228 @ .050.
