What the price range on those cams?

All under 200 bucks except for the custom cam. The TFS cam is ~139 and the X is ~189. Pick a cam with your goals in mind. This is one of the trickiest parts of a build Good Luck

TFS Stage one will be too small...go with a custom or XE274HR. That would be a good cam for you.

When I first put the 331 together it had a Lunati cam in there with specs that were pretty clost to a TFS stage 1 and a TFS street heat intake.

After putting in the xe274hr and a track heat intake which flows about the same as your performer intake, the car gained 44rwhp and dropped my et by about 7/10ths. That was also with swapping from a catted x to an o/r x.

Hope that helps with your decision .

I guess you made my decision for me. But smog is really a big deal to me and need to know before I buy it if you have passed smog with it yet. Thanks a lot that was the type of info I was looking for.

---

The best way to know if it is going to pass smog is to get a cam that has a CARB EO number like the E cam or the Stage 1.

However, some cams w/o EO numbers may still pass smog. The best thing to do in this case is to call the cam manufacturer and make sure. If you get a cam that does not pass smog it will be a lot harder to correct than bolting on your smog equipment.

The bottom line is you will be trading performance in order to be emissions legal.

i have the trick flow stage one in my 306 and i love it. you also have to watch out for your piston to valve clearance, especially with the ford x cam. my friend put the x cam in his 302 and bent all of his valves. so with the tfs stage one, has good power and sounds great at idle.
