Comp Cams as well as Crane Cams makes excellent roller/rocker cam and crank kits for the 4.3 Vortecs, most especially pre-98 4.3's. I've had much success with Crane Cams, only went with them for sponsorship reasons, but I've definately gotten my share of fun out of it. after that, it's all easy. Intake and exhaust upgrades with a wee-bit of weight reduction, and those things scream.
