Get a cam thats a little biased towards the exhaust side. I would buy a custom cam if you've got the cash, but if not I like the tfs cams.

Yo... Hows the blower install comming along?
Just keep that cam.
I fear the block will split so you really don't want anymore power.
But if you feel the need save yourself some work and change the pulley on the crankshaft to an 8" one. That'll make more power than a cam swap be less work.

The F cam is good for super or turbo chargers. Comp makes another good cam but I can't remember the numbers I am sure sombody else knows. The TFS stage 2 is a good one too but like somebody else said earlier the F will pass smog.
all in all Keep that cam and if you arn't satisfied with the power change it afterwards cause I think you will be just happy with that cam.

The F cam has been known as a great blower cam since before me and you knew what a Mustang even was Eric ![[patriot]](graemlins/patriot.gif)

For all those who have said the F cam is a great blower cam could you please tell me why you think it is so great? Also...can you maybe name a few "bad" blower cams.
I'm just interested in hearing some opinions.

Yes I know I said great and it truly is not GREAT, but an F-cam is certainly a better choice than stock. I don't know the ezxact science behind the cam and I'm sure you do. However, based on past knowledge knowing many people personally who run this cam on boosted applications it seems to do very well for them. I'm sorry if my replies are not up to your standards but I ay what I know and nothing I don't. I know a custom cam will definately make more power, and there might even be a few better cams off the shelf, but as far as my knowledge goes I know the F has bee capable for years on boosted apps. Could you give me reason's why the F is not good for boosted applications ![[Confused]](confused.gif)

The F works great with turbo's because it has negative overlap.
It works good in boosted applications in general because it has decent .006 duration & medium ramprates...not too aggressive, not too soft.
It works well in blower applications when installed advanced a few degrees (as ground, dot-to-dot). When it is installed advanced, it is significantly exhaust bias relative to TDC....maybe a touch too much for some blower combos (like AFR heads), but just about right for heads like TW & Edelbrocks...or any other head with not-so-hot exhaust. Again, it's really combination specific, as intake manifold, headers, H/X pipe, etc all play a large role.
But, for a smogable boosted cam, it's definately not bad.
The E303 is a poor choice for a blown application IMO. It comes with 0 advance, weak ramps, & has a bad reputation with reguards to idle quality.
The TFS1 is also good when installed on a 112ICL.
TFS 2 won't normally pass smog.
My opinion is the same as Slowhoe's. & the comp cam he is refering to is the XE274HR. Retard that thing to a 112ICL too for best results.

What about the crane 2031 I think those are the number, thats a pretty good cam for boosted applications.
Like 93pony said its all about the other things going into the set-up, shoot you see some of those guys running awesome with stock cams. It's all in how you set it up.
I don't know the science in it either, but 93pony does. The only thing I know is from seeing cars run with certain cams.
Now Mr.S what is floating inside your head??????

The crane 2031 is the E-cam so as far as a good choice for a blower goes that's out. I know there is a crane that they advertise as a blower cam though

The crane 2040 is like the E cam and the 2031 has more lift than the E but less duration!

yeah I guess I was thinking 2040, but if you check out a brother's catalogue, in one of the crane cam descriptions it says that crane provides this cam to ford and it is also known as the E303, I thought it was the 2031, but I'll double check tomorrow

First off, my post was not directed specifically towards you, and second I am FAR from a "cam guru". What i'm interested in hearing is what about a cam(dur, lift, overlap, LS, ect...) makes in a "blower cam"?
The fact that cars have made great power with the F cam doesn't really mean anything to me since virtually ANY camshaft(even the stock one) in a properly tuned supercharged combo will make great power and haul ASS!
Also...I see a lot of "cam gurus" state how head flow, intake used, exhuast used ect... are all key factors in choosing a cam and then I also see other "cam gurus" not really pay attention to that but just the specs of the camshaft itself(ramp rates, overlap, ect...)

I know duration is important and that you can always get more lift from 1.7 rockers if it's needed. Lots of picking a combo is also just matching power bands. I love seeing people with an intake manifold that is designed to make power only to 5500 RPM on a motor that wants to rev at least 700 more RPM. Even I know what a stupid combo is at that rate. If you know the history behind certain combo's that work, the rest really isn't important because history repeats itself. That's why I knew the F-cam was good for a blower, cause that's what it has been known for. I'd love to be able to understand things as well as Shaun, but frankly sometimes I thinkhe speaks in a different laguage. I'll just stick to asking him what works, and when he says why, just sit there and nod my head like I understand ![[Big Grin]](biggrin.gif) ![[Wink]](wink.gif) ![[Razz]](tongue.gif)

The 2031 is also not a bad choice for a lot of street setups. Especialy with heads like E7's & GT40's. Again, depending on total combo, it could use some retarding to work best.

First off the E-cam is not a bad choice for blowers. The F-cam is a better choice. DO NOT retard your cam with a centrifical blower(you are better off advancing it) like the SQ. The reson you don't is because you want the lower end tourqe you gain buy advancing the cam for when you are not under boost. You are going to make power when the SQ comes on anyhow. People have run mid 10's with a E-cam. your set up you have is going to run sweet just like it is with the SQ. I have a SQ with a power pipe and it pulls 12 PSI of boost. BTW get a good set of Autolite racing plugs set the to .030 or .028(depending on your ignition) when you install the SQ so you don't have to go through the spark blow out like I did it sucks.
