Gents; I rebuilt the 350 motor 15 years ago in my 80 Z-28. It has flat top cast pistons and home ported "993" heads and headers. The cam presently is the old SSI 214/224 grind and does pull smartly in all gears. I would like to have a bit more power and exhaust note and as such am considering a cam change. The auto is a 4-speed with 3.73 gears. I also have air conditioning and would like to keep it, so now for my question. In an effort at keeping costs down what do you gents think of the Elgin E-1166-P cam. It has 216/228 duration and .453/.480 lift figures and is ground on 112 degree centers. I believe the cam will have a noticable idle and pull like a freight train in high gear and best of all it's only 52 dollars! Am I off base here?
