1967 273 cam suggestions

273 two barrel pistons are about .020 down in the hole. You should have run 273 heads, which are the best, or since you have a 67 car, 302 heads at least for compression. To make the best of what you have now, if you have a hydraulic cam, something around 260 duration and around .450 lift using 340 valve springs or equivalent. If you still have the solid lifter rockers, shafts, and pushrods that is the way to go. I'd second the Racer Brown recommendation. Jim is easy to talk to and the higher cost is nothing to have a cam that will do what you want for the next 10 years. He knows MOPAR and 273 engines.
