It isn't that it can't be done, it is just that it is less than ideal. The rocker arm multiplies both the "good" and "bad" areas of the lobe. So, where possible, we like to simply spec a cam that will run with the factory rocker, even in instances where it is below 215deg. Either works, and everything is a compromise.
can we say thread jack? lol jk. ran the car at englishtown this past saturday. ran a 12.50 @ 112.8mph with a 1.98 60ft time. I know I can get the 60ft down a little more especially with those 315 BFG drag radials but I just need a little more practice.
Haha, yea it is kind of a thread jack. I saw this post and was wondering who you were 
Nice times with a crummy 60ft! Mind posting the 1/8 mile ET and MPH? Do yours 243s have any work done to them?
EDIT: Sorry just saw the posted slip

We've managed well over 400rwhp on 346cid by cutting the 241's and sticking with the OEM cams. If you like, we can supply a cam that will combine the positive attributes of both the LS1 and LS6 stock cams from the test.
Advanced Induction - How much would your modified 241's, ls6 intake, and one of your cams with stock exhaust make at the rear wheels? I think this would be a great sleeper with great driving manners.

Be careful what you ask for.. 
Reducing inlet and exh restriction is typically the first thing done, and for good reason. You can build a great sleeper, and the 241's have far more potential than people give them credit for. However, in all applications you will hurt the performance by corking it up. Now, if you're talking about running the stock catback w/ a decent set of headers, that may be worth testing, but be prepared to swap or bypass it for the setup to run to its potential.

Back from the dead - can anyone tell me why the LS6 cam got its *** kicked by the stock cam clear up to 5500rpm?
Im in the middle of doing a Advanced Induction 241 & LS6 cam setup and going by that dyno chart...I'm not liken what Im seeing there.

Pretty simple, the ls1 cam is geared more towards low RPM use. The ls6 cam may have lost some low-end, but even then the area under the curve compares favorably to any other heads/cam LS1 you're likely to come across. We generally just suggest guys let us provide an appropriate cam that is ideally suited to the goals.

Advanced Induction, if I am currently running and LS6 crate engine with pretty much full bolt-on's thru an A4 trans, what would you expect that I would gain via your 218 or 226cc port packages? Being that I would be retaining the stock LS6 cam (2005 crate engine), would I gain anything stepping up to the 226cc port work over the 218cc??
Thanks...
Thanks...

Thank you sir...
I gained 43hp from s set of out of the box AFR 205 heads. I was on a mustang dyno and I already had a cam,so i didn't switch. Later,i added a bigger cam and so on. The heads alone got me 4 tenths at the track.

I had a similar set up a few years ago, I bought a H/C Z/28 that I had to return to stock to smog. I left the heads on (Stage 2 TEA 241’s, circa 2002) and replaced the cam with a LS6 and threw the stock exhaust on back on. The car had 4:10’s with a stock Torque Converter. It was a blast to drive. The car would move out if you blew on the throttle, lol.
I just completed another similar set up but with a cheater cam…similar situation, I needed to smog.

The car is very funny to drive and I have a hard time keeping my foot out of it, lol.

About 10 years ago I put a LS6 cam and some GMPP 243 cnc'd heads on a 99corvette with boltons and had very positive results. 418 rwhp. It would trap 121mph. recently we took that cam out and put in a sponsors 224/224 cam that was laying around and lost a few rwhp and trap speed down to 118mph.
John Lingenfelter had a quote once that went something like-
a good engine with the wrong cam but good heads will make more power than a good engine with the right cam but poor heads.
I am sure I messed that quote up but the point is there. And although there are exceptions it is for the most part true from what I have seen.
