About a year or so ago, I decided to do more than just bolt-ons. I wanted more, but didn't want to create a beast. Ended up with milled 243 heads, and a Lingenfelter GT-11 cam 213/231 .61/.65 lift, 118.5 LSA. Car put down 385 RWHP, and 356 RWTQ through the stock stall, headers, ORY, STOCK CAT-BACK, and an SLP lid. Ended up slapping a Vig 2800 stall along with a 3.73 gear (drag radials 555R) for an 11.66 at 118.5 mph run. 1.69 60'. That run was also made with an open cut-out. Car consistently ran a full 2-3 tenths slower with it closed. This was at about 800' DA. Car ran 12.22 at 114 with bolt-ons, stock stall, and street tires on a 1.9 60' for reference.

Well, the high lift and aggressive duration made for one loud valve train. I have also been getting metal magnetically stuck to my oil plug. So I decided to try a different cam. No idea if the metal is related to the cam or not.

So I went with the Lingenfelter GT2-3 208/220 .58 118.5 cam. Changes since dynoing with the GT-11 include a weld in Magnaflow crossflow muffler, and the 2800 stall. No other changes other than a retune. Car made 378 RWHP/397 RWTQ with the GT2-3. So about a 10 RWHP drop considering the RWHP difference and the addition of a better flowing muffler. I did notice a slight drop in low end TQ, but honestly I couldn't plant all of it to the pavement before and I still can't, so it doesn't really make a difference imo. There is also a pretty big difference in idle. The GT-11 wasn't in your face like an MS3 or MS4 is, but it was noticeable. The GT2-3 idles completely stock. The GT-11 also wanted to pull/surge/buck a tad, and would also stall out occasionally. The GT2-3 does not do any of that. Its only noticeable when you stomp it. I honestly can't tell any difference from 3500 up. The track may tell a different story. Anyway, just wanted to throw my experience with these two cams out there for those wondering about doing a smaller cam.

One more thing, kind of a big deal imo. The GT-11 DID NOT cooperate with my stock converter. We tried everything to get it to work with no luck. Put it this way, the car would idle up to 15-20 mph and go into 2nd gear....without touching the gas, lol! The 2800 did the trick.

This GT2-3 will definitely work with a stock stall, I have no doubts.

I'll post up idle clips, etc, later on.

I know what you mean, my 224/230 cam with tune likes to drive itself in 1st gear lol...I def need a dyno tune after I get a yank 3600...also looking to go to a tick cam

Sucks doesn't it. That 3600 will more than take care of that problem. It'll definitely need a tune after you stall. My shifts were bouncing off the rev limiter at WOT until I got mine retuned.

A 224/224 114lsa is the biggest that you can go with a stock converter. Not because of a loss in low end but due to what your seeing. It tries to push through the brakes. Even going to a 112lsa is too much. The stall is for safety if you want to run a bigger cam.

You know you want to put a big *** lopey cam in there man haha Seriously though, your car seems to run damn strong for such a mild setup! If you and Greddy ever meet up again i'd love to run you
