I agree, pretty big for a 273, better have at least 3.55s and a loose converter. It'll lack low end torque. I went from a 224 @ 50 solid to a smaller cam. Gained a lot of low end, but lost a little on top. Gas mileage was terrible until about 70 mph. Then it got 20mpg.

Should be a good one. I used a Isky E-4 which is mild by comparison. (216@ .050, 260 advertised, .425 lift 108 degree.) I would like to hear that one run. It will like a little converter.
