The ASA Lingenfelter motors have been known to make 390-400 rwhp with stock unported 853 heads. Most used stepped 1 3/4" to 1 7/8" headers, a tuned and sealed ECU and the ASA 525 lift cam. They also used an ATI damper, and single stage scavenge only dry sump system that may have garnered a bit more HP. They are very torquey and pull hard to 6500., made decent, reliable circle track and road race motors. They were stock compression, so around 10.1 to 1.

I really don't see it at all taking a 1999-2002 F-body, putting that cam in and making 400RWHP especially with 853 heads.

Agreed^^. My car has zero emissions with full free flowing exhaust, not to mention a 3" electric cutout on tap after the 3" ory when i want. Im hopeful that with 10.8:1 compression and good flowing heads that i can make the 390/380+ mark. Especially with all the bolt on drag reductions I have, and through an m6. Im more excited about that high and flat tq curve this setup will make

Only thing that worries me about your setup is the springs. Normal ASA, LS6 all the way (that's what I've got). On the howards "asa" I would be a little worried. If the ramp rates are more aggressive it may end up taking a toll on those springs! Check them every 10k or so for issues.

In race car fashion or practical in a street car? I don't see an issue making the power without all the pollution mechanisms to include mufflers and Cats.

I don't understand why some are looking for miracle. You take an engine that makes on average 315 to the wheels, swap in a cam and thinking the power is going to jump 100hp.
You need the support the mods to do it. You need to get the air in and out effectively and efficiently. You need headers, you need a good intake, a good throttle body, etc etc...
380 RWHP is pretty freaking good!! I have had old school small blocks at made 330 to the wheels and that was awesome street power. Some people think they need more power than they really do.

There is more to the car than just HP. Today's F-body and Corvettes can handle the high horsepower because of the modern suspension and brakes too.
I would agree that 400hp engines are the norm these days with popular muscle cars, but I don't think we are 600hp quite yet for the average Joe.
I think for anyone who has actually driven in a car with mid 350-400hp to the wheels will say, it's plenty for a street car. Unless your car is strip only, there such a thing as too much HP.

I hope i can handle 400rwhp. Lol. I can handle a 150rwhp bike down a track, and my previous motor was a 490hp 383. I have a respect for power. It can be dangerous

500 crank hp can get squirrely...500 to the wheels and you better have a good set-up.

Just as i imagined it came out great. Ill post a dyno chart when i get to my computer. Made 417/397 on a stang dyno. I'm pretty sure it pulls just as hard if not harder than my 383 ls1 did. The torque curve on this thing is phenomenal!! This is the howards cam version of the asa, they claim around 9-15 hp more. And it asked for 10% LESS fuel at idle than stock. Idk what mpg i can get hwy yet. Cant keep my foot out of it!!
