I had this posted on a different site but you guys might benefit from the info
"I need some advice on a cam for a drag car. This car sees only 1/8 mile use. 1964 Chevy Nova. 3.73 gear. 26" tire. 2800 without driver. 3100 with. 400 block. de-stroked to 377. Flat top forged pistons. Pro top line aluminum race heads, 58cc chamber 200cc runners 2.02/1.60 valves. 3800 converter 350 trans. Holley strip dominator intake. Carb as needed. 150 hp nitrous as needed. Headers only. 1.6 roller rockers. Want flat tappet cam. solid is fine. I would
like power from 3000 to 7000. If something sounds slightly off, I was going by memory on these specs. Thanks "

doing some quick calcs and assuming youll use a head gasket of about .032 thickness your cpr is about 11.5:1 your going to require race octane fuel,(no suprise)the cam below should maximize the power off nitrous and work reasonably well with nitrous (JET IT RICH and back off on the ignition advance per the nitrous kit instructions

call crower and verify everything before you purchase a cam but with the limited info ID be inclined to go this route, assuming of course the clearances and valve spring rates and valve train geometry will be carefully matched to the cam, and you realize this is a hold your foot to the floor most of the time type of engine combo with a decent single plane intake,the engine going to be running over about 3500rpm when you launch and you realize your going to want about a 4.56-4.88:1 rear gear, those 3.73:1 rear gears will work ok, with the cam, but more rear gear will help in an 1/8 mile combo, and the biggest slicks you can fit into the wheel wheels, we used to build alot of similar engines
