When I spoke to my builder he said the stock Navigator cams are actually pretty decent for Turbo setups. He said if I wanted to, I could go with FR500 cams, but that's as aggressive as he would recommend for something that does a lot of street driving. Hit up turbomustangs.com and head to the Modular Motor section. Some of those guys are making serious power and have all kinds of cam specs.

i dont want to spend 1100 on cams for 15 rwhp ya know...


so thats why i am looking at the b headed cams and etc... stock cams are decent esp for the price... idk about the 03 cobra cams because they are blower specs really...

i will probably end up with a set of b headed cams...

When I had Al P build my engine, the ONLY thing he wanted me to replace on the top end were the springs. He said the 4V can handle boost very well, but for insurance, a beefy set of Crower/Comps is a good idea.

B Head cams are great for turbos as well. I wasn't even thinking about them. Of course "B Heads" are the in thing right now, so be ready to pay a little more than you expect for something that's a few years old.

If you want something a little less expensive than the available billets but still have an upgrade....I don't think you could go wrong with the higher lift factory "GT" cams. I have no idea what the specs are but I do know they are a little more than your standard 4V cams.

Yes I know they are blower cams but really ? There aint much difference if any.

They are junk !!

They grind too much off the lobe and then you have to shim the valve train to get your valve adjustment back into range and it is very half azzed.

You can't even regrind a 2V cam because the lobe will crack and fall off the tube. The 4V cams are the only ones that will hold up to regrinding but like I said ....it is half azzed.

Where does the 10 rwhp number come from ??

The more air you push thru the engine the more effective a cam change will be. If you build a dog....it will be a dog with billet cams. If you build something that runs hard the cams will show there worth very quickly.
