Just another cam pick question.

The 484 cam is darn good and in that set up should be in the mid high 100's for MPH. 110 mph isn't out of the question. If it's the 114lsa model, barf... Depending on static compression, the 108LSA install it at 100-102 instead of 108 recommended and it will have a bunch more low end grunt.

Ignition timing, better converter, carb squirters/cams, tires, degree cam are all places I'd look before changing camshafts.
