thoughts about 273er combo

My experience with cams in 273's are stock solid Commando, pretty sweet. 284 duration solid, pretty strong. Used 340 stock cam, 1.88 intake J heads and 71 340 intake and TQ, Wow! All got 20's for mpg cruising highway. " 69 Cuda 440" did a 273 cam comparison in a 67 4 speed Barracuda, If I remember correctly. Very informative. I'd say if you tune your engine correctly and your cylinders sealed up, good valve job, good bores and rings, you should be there.
