If you are going to use 4.10 gears, then you need a cam with 280 seat duration. I prefer solid lifters. In fact, I detest hydraulic lifters.
Don't know the intake but if it's single plane a good 650 double pumper will work. If it's a dual plane, make the carb a 750.
You can get a Pro Form carb from jegs. It will be all billet and fully adjustable. Don't skimp there.
Make sure your headers are 1 3/4 or 1.750 diameter with a 3 inch collector.
Just because I'm a redundant guy, you should spend the few extra bucks and get a CUSTOM ground cam. I've posted many times some of the companies I use and some others.
If you are bound and determined to use an off the shelf cam, I'd make sure the LSA is no wider than 109 and a degree or two less would be better.
