Hey guys I am trying to get some advise/opinions on these cams before I swap cams out in April. Which one would be better for the task at hand the Lingenfelter GT 2-3 (207 int, 220 ext/lift 578 int, 581 ext, lsa 118.5) or
Speed inc SC1 (224 int, 232 ext/lift 581 int, 595 ext, lsa 114)? And of course the supporting cast will be added at the same time. Any input is welcomed.

Here is the graph of my Hawk with a 6 psi powerdyne (you can see where it starts slipping), GT2-3 cam, and ARE heads through Mac headers. I liked it because it had stock driveability but still made big power. You could probably make more power with the other cam, though.

I have the GT2-3 cam in mine, you can see my setup in my sig.
The speed Inc cam would be much better for a N/A setup with the high duration, and tight LSA. The GT2-3 will also makes it much easier to tune.

i ran the SC1 on my blower setup and it made great power and was very streetable

Hey James. Glad to see you got the fmic/mondo going. How do you like it so far?

As for the cam, if your tuner is sure he could tune the sc1 without any hot/cold start up, surging, etc problems with an A4, I'd go that route.

I'm selling my gt2-3 within the month. It was a nice cam, but I now have a cam matched with heads going on. Which is in between the two of them.

I picked up 2 pounds of boost with the FMIC/Mondo BPV (total of 13). Therefore I had to pulley up from a 3.4 to a 3.7, now I see a max of 9. As for the Mondo BPV, that combined with the 3600 stall equals "loud portable leaking air compressors" until you hit 40 mph. Then it quiets down. Runs good though.

Im running the SC1 cam with near the same combo and I have no drivability or idle problems at all, Even at cold start up it does great. I was a little dissapointed that it still had a near stock idle.

With same combo and stock cam I was making 508Rwhp at 13#, with nothing more than the SC1 cam it now makes 570Rwhp and shows only 10#.

I like the part that it has a near stock idle, I do not want to sound like John Force at the stoplights. Where is your redline set at?

Jeremiah

We set it at 6800.

I wanted to set the rpms at 6500 or 6600 rpms, but if that wont do the job then I'll have my tuner set it at 6800 rpms also.

Any other "off the shelf" blower cams available? I was thinkin' somethin' a little bigger for a stroker motor...

Speed Inc has another custom grind, their SC2 226/234 117 blower cam as well.

Thanks! Is lift just not all that important in a FI set up? I see duration and higher LSA being the main factor in a good blower cam...

Important thing is to set a goal, and then pick the duration.

I have been running a custom 236/246//114, lift is like .590/.620 but who cares.

I have the GT2-3 cam. I had the G5X3 and was tired of the big cam thing. I wanted something smooth, gets good milage and isnt a bear to tune.

its hard to recommend something when we dont know the secret blower cam you already have

NBM~01~WS6

What would be the the average horsepower difference between the 2 cams??

Given you have a stock ls1 with full exhaust and 8lbs of boost..
