If the ASA cam makes good torque

His car made a best of 409 rwhp peak, however his area under the curve was to this day the best I have ever seen on a 346 hydraulic car. This was all with a set of POS heads that only flowed 260 cfm. With some better heads, that car would have made 430+ rwhp and prob. 420+ TQ.
It's a good cam, get your car tuned by someone who knows what they're doing, and you'll like it a lot.

Humpin, it's been a long while since that setup was around. That tune is long gone.
I would NOT recommend a mail order tune for this cam. I needs to be on a dyno, and tuned properly.

John B, where did you get this information? I would like to learn more...
Here's the quote from Jim Hick's (LS6 Camshaft Engineer):
"In fact, we ran the ASA (the American Speed Association, an oval track racing spec. series that uses a modified version of the LS1) cam, back-to-back with this ’02 LS6 cam. If you don’t change the exhaust system, you only pick-up 2 hp with the ASA cam, but if you drop the back-pressure to something near zero (ie: a racing exhaust), then it’s more like 20hp. So, that’s the back pressure effect I keep talking about."
What about that ASA cam? It’s got only .525-in. lift but, at .050-in., it’s got 226° intake duration and 5.5° overlap versus the LS6’s 204° and no overlap. Clearly, it’s designed for higher rpm and more power but it needs a very low restriction or open exhaust. Will it work in a hi-po street LS6? Well–kinda sorta. Once you get the cam and the right valve train pieces, the biggest problem comes if you have to remain emissions legal. Getting the engine to run with the ASA cam but without the OBD2 diagnostics blowing codes would be a challenge you have to tackle–but only after you design a cat converter set-up and exhaust system that has low enough back pressure such that the ASA cam’s potential can be realized.

It seems like 1.8 or 1.85 roller rockers would work well with this cam. From what i see this cam, rockers, and a good set of heads, with bolt ons, should yied 420-430rwhp, I think it would be cool to use because it lopes hard and it would be something different than what everybody else is running.
I also considered the 1.8 rockers as well to help with the lft. I think this combo with the Fast intake and AFR heads would prolly be killer but right now that is just speculation because 2 of the components arent available yet.

Mean Machine, I sent the flow sheets out to you. I never heard from you again so I assumed you got everything. As for them being POS heads, I dont think so. They were a 2 yr old hand ported set of heads.As Damian said, they didnt flow like the 330cfm heads we have now, but they damn sure made the power. I have PLENTY of dyno graphs and time slips with that setup. If you have a fax machine I can fax a few your way. I did make 400ftlbs @ 4000 RPM and had one of the flattest torque curves I have ever seen on a 346 hyd.No, the car didnt peak very high,408rwhp/406rwtq, but it did the job under the curve like no setup I have seen.
Did you ever install the setup or did you sell it? Shoot me a PM man.

Ive been trying to find the old ASA cam threads, but no luck. I know someone here was running the ASA cam with the GMPP LPE CNC'd heads. I'd really like to see some dyno graphs of this cam, and especially with the GMPP LS6 heads. Im having a real hard time deciding what setup to run since I dont really want to rev past 6500 RPM with the stock bottom end. The under the curve of this setup should make for a very quick street car. Any more info on this setup would be very appreciative.
Here in Sacramento Ca, I run the std hotcam in my M6 SS and my roomate runs the ASA Hotcam in his 99A4.
There are some tricks to assure the proper setup in the hotcams from what I have found. Buy asking a GM powertrain rep I have be told the to use 1.8 rockers on the cams to get full desighn of the profile.
I guess they are spec. for .555" to take full advantage of the stock head and intake flow. Who am I to argue with GM.
But know complaints here with the hotcams. I mean I have seen (been in the car) when a 420+rwhp H/C M6 car could not pull a bolt-on ASA A4 with stock heads.
And as for drag racing well the ASA gained a new best for his car even when launching in 2nd gear. ( still trying to figure this one out) So needless to say the ASA WILL work for dragracing. When the season opens again we should see 11 sec passes out of it with no weight reduction.
hotcam'ed and happy,
Mike

Who makes this "ASA" cam? Do you all think it would well in a 6.0 with ported heads and some spray? I am asking since you all sy this is a tq monster and I am assumgin that the extra cubes would mean even more tq.

That cam does need a set of aftermarket rocker arms to really shine, but the one good thing is that its real easy on the valve springs, even on the ls6 ones. Thats one thing I like about it, if your trying to build a reliable heads/cam package that doesn't need new valve springs every year depending on how its driven, etc.
