road car cam for my 318

For the OP, the Summit K-6900 RustyRatRodr recommended is what I've been running in my 318 for several years now. I've also got a 600 Eddy on a Performer intake, duals off stock '74 manifolds, stock 904, and 2.76 gears with 27" tall tires for the time being. I've also got a decent ignition curve thanks to help from the gurus on here, with the initial set at 12 degrees. I would say that low-end is no worse than stock with a much stronger mid-range. I consistently get 17 mpg with a mix of 2-lane 60 mph driving and city driving. I don't run the car super hard but generally accelerate fairly briskly. I feel pretty confident it would knock down at least 20 on a highway trip. As a side note, initial start of the engine when I installed the cam took way longer than it should have due to not having the ignition timed properly and the cam still survived. I just thought some real-world info might be helpful.
