RE: Cam question
Cam Style: Hydraulic roller follower
Basic Operating RPM Range: 1,800-5,800 RPM
Intake Duration 050 inch Lift: 234
Exhaust Duration 050 inch Lift: 238
Duration at 050 inch Lift: 234 int./238 exh.
Advertised Intake Duration: 270
Advertised Exhaust Duration: 274
Advertised Duration: 270 int./274 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.550
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.550
Valve Lift with Factory Rocker Arm Ratio: 0.550 int./0.550 exh. lift
Lobe Separation (degrees): 113
Intake Valve Lash (in): 0.000
Exhaust Valve Lash (in): 0.000
Computer Controlled: No
Grind Number: XE270AH-13
They are ground on the XE lobe which is less agressive lobe in the Comp line. However that is alot of duration for only .550 lift. I am not familiar with what the piston valve clearance is like on the 4.6 motor, but personally I would like to see a little less duration and more lift esp. if want good street manners.

I picked up about 30 RWHP at the very top of the RPM band, but not for very long. I also lost some torque down low.
There are better things to do with the cash than install cams. It cost me nearly 1700 dollars once I got it installed and tuned (had to buy a new chip). I coulda done it myself at my dads shop, but it is a pain in the ***, and it isn't that hard to screw it up.
If you are really interested send me a pm and I will send you a few before and after dyno picutes. I would post em now, but I cannot find em atm.
I think I will have to talk to dan about making a sticky about cams. I think alot of people have a miscoception that they will pick up a ton of RWHP without headwork and a forged bottom end.

I have to agree with 2000GT4.6 everybody wants the big but don't realize that there are better HP/dollar mods out there. The big problem is that a big cam just sounds cool, but everyday drivabilty can suffer.

I am also intreasted in this, as I have started to look into getting a set of cams and heads for my car. I do not really want to do anything with the bottom end. But I was defently looking at getting either a set of stock heads and P&P them or buy a set of aftermarket heads with a P&P job already done. I would like to stay N/A so I do not want to use nitros, and I can not really afford a supercharger. I am looking at purchansing parts for this over the next year or so and once I have all the parts save a little for the install/tune and have it all done. So the big question is after full bolt-on's what is there to add if staying N/A? Thanks for any help.
