OK, I have my cam selection narrowed down to three. The car is a 1990 coupe, ported E7's, ported stock intake, 65mm TB, 73MM MAF, 5 spd, 3.90 gears.

Comp Cams XE266-HR

Advertised Duration 264/270
Duration @ .050" 212/218
Valve Lift .512/.512
LSA 114 deg

vs

TFS Stage 1

Advertised Duration (Degrees): 275 intake/279 exhaust
Duration at .050 in. Lift (Degrees): 221 intake/225 exhaust
Lift with 1.6 Rocker Arms: .499 in. intake/.510 in. exhaust
Lobe Separation (Degrees): 112

vs

Speed Pro

Advertised duration: 289 intake/289 exhaust
Duration at .050 in. cam lift: 212 intake/222 exhaust
Gross valve lift: .493 in. intake/.510 exhaust
Lobe separation: 112 degrees

Prices are similar on all, only difference is that the XE266HR is used.

Lets here what you guys think

just buy the comp cam new - why get a used part that is such a crucial part - even new it cant be more than 225-250 - and how much are you getting it for? If your saying they are similar in price, well the TFS S1 cam goes for about 200 bucks - so whats an extra 25 or 30 bucks?

IMO you should always buy new ****!!!!!!!!!!! I dont trust anybody ever anywhere unless you are on this site and have over 2000 posts lol

TFS and E cam are very similar, -- actually with your set up, having stock heads (ported) and a mild set up, your best bet would probably be a mild cam, .512 MAY be a little high lift, wait for the gurus of the site to help you -

Example - At atco, guy w/ 5.0 had edelbrock heads and F cam (.512 lift) only had 1.6 roller rockers - car flew - dont know if .512 would be too much

I am a fan on split duration cams. Therfore, i would get the stage 1. however, it seems that the speedpro is a slightly more agressive version and might give ya a tad bit more performance.

there is more to a cam than lift. the duration is a big key too. i would NOT worry about using an F cam and stock style heads as long as the P/V clearence was OK. I bet that it would be really strong up to like 5800 rpms (depending on heads/intake).

Ported heads + TFS1 cam = excellent combo. Great improvement over the stock cam.

I just installed the TFS stage 1 cam. It actually just started up today and I am really really pleased so that is my choice for you.

my tfs stage one went in four days ago, and all i can say is yeehaw. nice mean sounding idle too. it also helps that the twisted wedge heads and eddy perf 5.0 went in at the same time.

To be honest, I'd tell you to keep the stock cam until you upgrade your heads/intake. If you do buy one, I'd say go with the TFS-1 if you plan to stick with your current heads/intake for a while. Otherwise, I'd go after the comp grind.

As someone else stated, I'd feel a lot better buying a cam new. Granted, it's really hard to injure a roller cam, but I personally wouldn't take the risk.
