Mike:
That is a very mild cam, it should idle almost dead smooth. I would go for some more duration and lift, keep the lobe seperation at 110 degrees or above. Cams in brand new Corvettes and Camaros are only about 10 degrees less than the one you are looking at. FE's like duration more than many other engines. I have a stroked 427 with ported Edelbrock heads. 258 / 260 degrees at .050 and .620 / .625 lift. Idles at 850 rpm all day. Made 585 hp on pump gas @ only 6,000 rpm. Now you don't need anything that big (I've got more inches, and heads are ported), but you can go another 20 degrees with great idle and off the line acceleration.
