I was thinking I need a little more lump in my idle since I got my tune right. I was toying with the idea of putting my idle back to 800 (from 900). That should do the trick I think.

The GMPP heads are an excellet deal for anybody wanting to upgrade their top end without spending a ton of money. These heads will flow over 300 cfm @ .600" and sell for under $2000.00 for the pair outright! This is for new LS6 castings with lightweight LS6 valves.

Members wanting to stay away from a big nasty cam should look at our GT2-3
it's specs are 207/220 .573/.580 118.5 so it gives you good power through the RPM range without giving up any driveability. You could run this cam without any tuning and be very happy with it.

You'll sacrifice 15-25 peak hp in comparison to today's more contemporary cams. The compromise is an excellent tq/power curve.
My only experience regarding the ASA cam is that of my online inquiries with those who've run the cam (much like your inquiries Kenny). From what they've told me, it can be used as a daily driven cam. I would think however, that more contemporary aftermarket cams would be much tamer for daily drivers, yet achieve similar/much better power output.

As for reliability, most any heads/cam package from the reputable suppliers will not compromise reliablity. I've driven my setup clear across Florida, dropped the PSI in the rear tires, run several passes down the 1/4 with 5K clutch dump launches, put air in the tires and driven back home.

asa cam

I drive my vette most dry days. I avergae about 26mpg hight way but about 15-17 around town, I love the way it sounds at 2k rpms so thats where I keep it, but it only surges when I cause around 1k to 1200 rpms. I had it idling at 850 for a while and it was extremely rough, but consistant. I raised it to 900 so I wouldnt make my *** numb. Other peoples dyno graphs will look better but you compare there track times and money invested, it comes up close.

not to rebirth an old topic but I've been considering the ASA cam myself and was wondering about running LS6 springs on it vs. something a bit larger with some 918's. I'll be tossing it into a 6.0(which also makes me wonder how well it will do) that will primarily be a track car but also a saturday night brawler/crusier as well. Full manual th350 (shifted @6500+-), 3500 converter, carbed(performer rpm and a 750dp) 3.90 geared 9". Just needing some thoughts since this will probably be my biggest stumbling block and possibly my biggest regret one way or the other. Thanks.....
oh, and I forgot another important thing, it will definately be seeing a 150 shot later on after the combo has some running time on it for suspension tuning etc. I'm trying to keep my hopes of some 7.0's (1/8 mile) times a reality while still being able to street drive it. If it will run mid 7's n/a and a 7.0 with a 150 hit I'd be extremely thrilled..... thanks again
