Best Cam for 302

[olddog]

The most important thing, is make certain your cam swap doesn't destroy your engine. Increase in lift, durration, and ramp rates results in less piston to valve clearance. If they hit you will loose the engine. Next, too much lift for the springs. Depending on the springs, valve length, and total set up there is a maximum lift before the coils bind.

For every cam there is a specification on required spring fores. Most people recomend changing springs with the cam.

Now you have to decide where you want the engine to make its torque. There are compromises and you cannot have it all. One compromise is street manors.

I think your manifold is dual plane. Most dual plane intakes give great low to mid range, but suck at top end. Single planes just the oposite. You should look at the rpm range for your intake. A high durration cam with an intake designed for idle to 4000 rpm will result in a dog just about everywhere.

My point to all this blabber is you need to give more information about what you have and what you want, before anyone can give you good advice. The cam manufacturers should be able to tell you a bunch if you give them all the facts. Especially the car weight and gearing.

I hope this helps you.

PS
How many rpm are you willing to turn your engine. Don't build it to peak on hp at 7000 if you are not willing to turn it to 7500. Your hp should peak about 500 rpm before your shift point give or take depending on gearing.
