Mild LA 318 Cam Recommendations from Those Who Know

I vote for 3.21/3.23 gears. If running the regular Edelbrock performer, deep porting it to 360 gasket match is worth some improvement. I would imagine even more so at that altitude. A set of magnum manifolds or shorty headers may work in your engine compartment and definitely be worth some power. At this weight and performance level, I would absolutely go with a Crower 267 HDP. Very smooth and drivable with a nice sound at idle but plenty of torque for 31 to 32 inch tires with 3.21 gears.
