Cams are not really hard. Everyone will have an opinion on them and have a valid point to there choice. Key points for your own choice in a cam would be;
Duration. This is the power band it will operate in. If your thinking is to have the car perform in the 2,000 - 6,000 RPM range, then you'll look at cams in that power range. Durations will be slightly different since Hyd. , solid and roller cams all perform alittle differently with there given duration.
Lift. You'll want to find a lift that will work with your head. If it is a stock head, generallly, the stock heads flow stall at around the .500 lift point.
This is why knowing how a head flows is so important to alot of people here.
Theres no real sense have the valve lift to .570 when the heads flow stalls or gets real crappy @ .500.
Hyd. or Solid or Hyd. roller or Solid roller?????? UGH! Theres alot of grinds out there. Choice on style is made easy but not limited to any one style. For a basic street machine, a regular standard Hyd. cam will do well. Don't expect a miricle from it, but it can make nice power, be easy on the wallet and free from constant adjustments or hang up from long duration cams with heavy springs and adjustable rockers etc...
