I was interested in getting a mild performance camshaft my 98 5.9 Magnum 360. Currently it has a 650 holley carb, crosswind air gap intake, and headers.

Any suggestions on what kind of #'s I should go with? It'll be a street/strip application but would like to do as little valvetrain modifications as possible and want to make sure I'll have enough PTV clearance (stock internals/heads). I'm going to order the GM 3.1 springs and 2.2/2.5L retainers for the heads. I have a 2200-2600 stall converter and 3.23 gears, but may be upgrading the gears to a 3.55-3.91.

I'm not sure what the limits are for regrinding cams. I called Bullet Cams and they weren't too much help on what I should do.
