Oh I never knew that. Thanks for letting me know. If for some reason the 350 I'm getting doesn't work out I'll look into a 350 vortec

You're right on the money Firebird. A lopey idle is the sound of a motor being inefficient at lower engine rpm's as a result of the extended intake valve closing point that is necessary to make power at higher rpm levels. It was not ground to operate in a street motor. It was ground to operate at the rpm levels necessary for making horsepower in a race mode. In a street motor, you need to make power from 1000 to 4500 rpm's, not 3500 to 7000 rpms. Using a race cam in a street motor tags you as a poser, a guy who is trying to make others think that he has a race motor in his street machine. A street motor that will operate on pump gasoline needs a modest static compression ratio (9.50:1 limit for iron heads, 10.50:1 limit for aluminum heads) that will support good power without detonation and a cam that matches up with the SCR. And like I said, the old guys who know better will just laugh at you when you come loping through the Sonic Drive In. The only guys who will pay attention are the mutton-headed freshmen who don't know anything anyway.

Ok, thanks for the advice. Do you guys think this cam would be good for my engine style? Mostly street use but may take to the track every now and then. The cam is a summit cam, part number is SUM-1069 and Advertised Duration 280/280, Lift .443/.443 . If this is not a good choice could you guys put a link for a good cam?
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
