Sorry to bring up an old thread but I have a quick question. Will the stock pushrods work w/ this cam and unmilled 243 heads? My feeling is that they will but I wanted to be sure?

Ok guys, hopefully I can answer some of these questions for ya. 1st- That was my dyno graph posted up earlier in the thread. 2nd- I have a M6 with 3.42's that I don't plan on changing. There is very lilttle surge @ around 1500, but only in 3rd & 4th gear. I can run 60mph in 6th all day long even with the AC on with absolutely no problems. 3rd- This is my daily driver (50-70 mi. a day). 4th- I'm running the 7.425 pushrods, LS6 springs w/stock retainers, and the valvetrain is very quiet (no ticking or sewing machine sound at all)
I am still running the stock (descreened)MAF with no problems. The guys at RevXtreme tuned my car and did an outstanding job! My only complaint with this cam is that every once in awhile, my O2's act up and throw the switching codes (typically in cold weather), but thats a small price to pay (since the codes dont affect performance) for all of the good things I like about this cam.
On a side note, to answer the question about why people dont like this cam, I think its many reasons. 1) its an older cam 2) its made by GM 3) low lift, and bigger is always better right? 4) not a lot of people know about it.
I hope this was helpful to some of you guys, and I could answer some of the questions you had!

The more i read on this cam, the more i liked it! SO, i went ahead and bought it today. What sold me on it was i got, cam,Ls6 springs and extra retainers from the local GM performance dealer for $450 and will be here in 3-5 business days. I have low miles on the car so i didnt think that i needed to change the chain or pump. So i guess what im trying to say is for $450 and have right @ 400 RWHP with the ASA cam, OR you spend a $1000 and get 20 more RWHP with other MONSTER cams, i think the math is simple. And not to mention the QUIETER valvetrain, and dont have to bother with the possibility of breaking valve springs.

I'm still not sold on the belief that bigger lift cams make the car quicker down the track. I'll have a stock weight 6 speed cam/bolt ons. Stock rear end, this time stock gears as well. I had a 224/228 cam that ran 119.3 on DR's with a joke of a launch. I am wondering if some of these "big" cams just pull really hard up top but are much softer down low compared to the "little" cams. Then again, my little cam was only a few degrees less duration and .581 vs .595-.612. Ideally, I would want max gains in the lower to midrange section and well as up top, which I"m sure the grind that Patrick G spec'd would do. So many barely make more power than stock down low but pull like an animal up top. That's great if you have a 12bolt/9" and are launching on ET's at 6200-6400. But that's about it. JMHO. Correct me if I'm wrong.

Anyone seen this cam by Edelbrock... i just came across it on summits website..
since summit is not a sponsor here.. i cant post the link or price... but here are the specs
230/237 .540 .540 110LSA
slightly larger than the ASA.. and slightly less money than the ASA
not sure what kind of lobes Edelbrock uses... anyone know? part # on summit is EDL-2216

Are there any other similar off the shelf cams out there that are as easy on valve springs as the ASA? It seems everyone is after high lift nowadays, and I don't care to have the hassle of changing/worrying about springs every 15k miles. The ASA may be just the ticket for me. Anybody else have any ASA dyno sheets? Thanks

1) bigger duration at .200 which helps with power throughout the cam's effective rpm range, not just the high end.
2)High lift cams generally have faster ramps from .006 to .05 which for a given duration at .05 makes for a little nicer idle.
Take the hotcam, roughly 218/228 112. Build it with a 218 XFI intake lobe and 228 XER exhaust lobe and it will make more power pretty much everywhere from 2000 - 6400 rpm and will be a little easier to tune for idle.
Whether it is worth it for someone who puts a lot of miles on his car each year, well that's a decision that we all wrestle with.
I'll change my springs once every 2 or 3 years and get the full benefit

Launching!
well the hotcam and ASA apparently have smaller base circles than the stock cams, but people run them everyday without catastrophic failure and live with a little valvetrain noise, I can't hear my valvetrain over my open headers, so I think its fine
