E or F cam
 

I have a 85 GT with a 91 stock short block it has a E cam edelbrock heads & holley carb. best run is 12.28 at 109.74 on 26-8.5 mt slicks on stock suspension. I pick up a B+M 144 Blower that i'm puting on the car is it worth putting in a F cam. The combo i have work's good. I only considering the F cam because it's free. Thanks

12.28 with a stock motor, e-cam, heads, and a holley carb. I call BS on that. Unless you have nitrous or something. I would say it's not worth going to the F from the E. There are better blower cams out there if you want to swap cams.

i recommend the f-cam. it gives me a little bit more mid to high end power and has a rough idle that i love. :D

If you can get the cam for free, then why not? It is a little more blower friendly than the E cam, but there's not too much difference. If you have to pay for it, then go research another cam.

Impressive time with those mods, I know the Edelbrock heads are underrated that's for sure. I'm running 106-108 mph range and can't hook up (never been on slicks tho). I've trapped 115 on a 125 shot tho.

No reason to doubt his claim. Heads, cam, probably intake. I didn't see where he listed the intake or carb type, but running low 12's at just under 110mph is reasonable to me.

The E cam has proven itself solidly compatable with blowers. I'd probably just stick with it and not open up an engine that's running good. If you aren't satisfied, you can always swap the cam later. Besides, the block won't take much more power than what you're already going to make.

is it posible that you can put a cam that can ad up to 50-75HP on a stock stang?

No,it's not possible...need to add more then just a camshaft to get these HP numbers

The only way you will see a 50-75hp increase from a cam is if you start with a 94cobra cam in a 900hp turbo car then go to a custom ground cam :)

You can add 250hp if you have a stock 2bbl mid 1970's 350 Chev though. Get a cam so big you have to set the idle at 1500-2000rpms, and of course you need a 1050cfm carb, and a Victor intake. Keep the stock heads, and stock 2.33 gears.

I can hear the bog now.

Fffwwwwwooooooooooooouuuuuupppp

I'm wondering why I got an email saying I called you a BSer. I don't think my post said that, in fact didn't I say that I think its possible?? Please re-read my post and don't send me any email until you re-read it.

How about 12.3 @ 112 with a stock lower end, E-303 cam, Trick flow heads, and a Holley intake. That's what I run on motor.

His numbers are EXACTLY what a good running 302 should do.

That's what I figured too, I think its possible, I know my car has the potential (although not there yet) to run that. I got an email from user 6037 that was pretty much un called for. I don't think my previous posts called BS on him at all.

He may have accidentally thought you were the one that posted 2nd on this thread. He's the one that said he calls BS on that.

or then again, maybe he just understood you. I really dont see how he would have from what you said though?

I said BS. I don't care what you say. Heads, and cam don't give you 2 to 3 seconds over stock. And without the heads and cam it would be a stock high 14 second motor. I have basically the same set up and on slicks I go in the mid to high 13s and I am a good driver. I'll keep my posts in the classic forum so I don't see bull **** like this anymore.

just because your car isn't as fast as others doesnt mean that you should sit there and call BS on them.

Are you telling me the guys in the NMRA that run low 11's with BOX stock gt40p heads are BS'ing?

what about Rick91GT and the many others that have run high 12's N/A with the stock heads/cam/intake?

he very well may be BS'ing but evidence shows that its likely that the car is capable of such times.

I guess I must be lying too. :)



Relax pal.

Anyways back to the original question.
With a Roots style blower you definitely will want to switch to the F cam, or else you'll be blowing a ton of boost out the exhaust due to the overlap the E cam has. There's a big difference between a 110° LSA and a 114° LSA.
Centrifugals get by this moreso because their power is of the high RPM nature and they aren't as cam-affected.

David put your money were your mouth is and bring your car and money to n.j. and i'll take them both. I'm no BS'er.Everyone thanks for the support.Sorry 86GT about the e- mail.

My car doesnt run good for its combo and it goes 12.5@107 w/ heads,cam,intake.

Your GT40 heads arent the greatest and probalby your car isnt tuned well.

If you werent an *** we could help your car out too.

true, but heads & intake coupled with the intake, carb, headers, pullies, gears, trans mods, and other mods he might have, would

Ok, he stated that he had heads, a holley carb, and a e-303 cam. He listed no other mods, so how can you say you have basicly the same set up if that's all you know. You know nothing of the intake he's running, the carb cfm, gears, exc.

Just because your car runs mid 13's on slicks doesn't mean his can't run 12's. exgmguy, skyler, and many others are proof that heads, cam, & intake can run 12's

Yes maybe you should confine you posts to the classic forum, that way WE don't have to deal with YOUR bull ****.

My Full weight 93 Cobra has been a best of 12.85@108 on drag radials with a not so impressive 1.95 60ft, I know it has 60's in it with a better 60ft, put slicks on it and who knows, but its to nice of a car to abuse at the track every week. The heads have never been off the car only additions other than your average bolt ons are E-Cam , motorsport valve springs, . The E cam has proven itself time and time again people can say all they want about custom grind cams but I am more than happy with my E!

Apology accepted and thank you.

Getting back to your question, from what the others have said and the style of blower you're going to run, I'd suggest the F-cam for sure, that and like you said its available to you.

Trey- 109mph! DAMN! Now that is almost unbelieveable on gt40 heads and cobra intake.

You got a crazy car.

Skyler

you can't campare engines even if there the same combo you can have 2 of the exact smae engines and have 2 diferent times. it all depends on who built the motor. and even if there stock engine cause you never know who took what apart.


it's highly possible for him to run 12s. just my 2 cents


ford kid

My car has always mph well. I seriously beleive that the car will run 60's for sure on Drag Radials, and maybe with a tad more mph, the pass before the 12.85 I ran a 13.02 @108.2, this is a full weight car and all, its a cream puff but at the track I drive it hard and do all the little thing like ice the intake and pull the spout out and set total timing to 34, little things make a big difference, also that pass was on welds not sure of the exact weight of the car. Later!
