If the ASA cam makes good torque
If the ASA cam makes good torque all throughtout the RPM range and torque is what accelerates the car, how come more members arent using this cam for drag racing. Instead they seem to choose other cams that seem to have around the same duration with the exception of the lift on the ASA cam and an aftermarket cam.

Good question. ASA's low lift would require less spring changes also. I've always liked the ASA, but few people run it. Guess we're all (myself included) swayed towards higher lift.

A guy locally told everyone how his car would dyno 400rwhp with that cam in his car (on stock heads) and it only ended up dynoing in the 36x rwhp range if I remember correctly.
It never ran well at the track either. After seeing poor results I just wasn't sold on that cam.

why would you ever have to change springs again after adding the ls6 springs? The lift is only .525 on the asa cam and those same springs come in a stock Z06 with like a .55x lift. Does it have something to do with a more aggressive ramp rate?

With high lift, agressive ramp rate cams, the springs see a lot of force and thus a lot of fatigue. A lot of people change them every now and again (say, once a year) to prevent the dangers of breaking a valve spring.

That's why I went with GM's hotcam. It makes good torque...

Yes, what Tommy said.
I would like to see dyno numbers/track times if anyone has them, it seems like it would be a good cam for the street, being that it should make good torque, and you wouldn't have to spin it extremely high to make good power.

I am working on a cam design that occurs very often in drag racing....a large split.... you got 10 on the split...thats about what I'm ending up at....but I'm going with less overlap to get more down low torque cause I have a daily driver....soon as I get some more money in the bank my experimental cam idea is gonna happen.....probably through brett bauer of bauer racing.....
its all about valve events...you get 11* overlap on that thing if its no advance ground in.....
bracket racers do a similar thing in limited lift classes...increase duration and splitto get horsepower in the upper end....but you loose a lot down low....for a street car...its just not a good choice.....but if its all track
and you will get some good spring life out of it too....

there is a local guy around me I think with a ASA cam he runs 12.60s@ 110, on the other hand my buddies car with a TR230, runs 12.0 at 118 both stock headed cars. I have never seen anything good from the cam, period. I think with the CNC LS6 heads that gm released its a awesome combo since they compliment each other well.
This cam is a great cam, but needs TUNING. Without a good tune, it's not going to run well and most certanly will not run well with stock tuning. That's probably why some people are seeing poor results with it.
A buddy of mine ran this cam for a while, the car felt SICK on the street and he pulled on plenty of 420+ rwhp LS1's. 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.
