Best heads for 500hp?
Grinder.. I find it odd you save face once Scott comes in and vouched for Doug. Rob literally did this years ago and you don't question his car. But Doug is full of ****?
There's way too many people on this site and cf that need to get their heads out of 2005.

Darth posted 539rwhp. His car is pretty advanced from the average head and cam street car. Pretty trick parts.

Has nothing to do with saving face, and I still dont believe a bolt-ons LS6 with totally stock internals went 10 flat, and reiterated it. I apologized for saying what I did because it wasn't right, had no class, and I was wrong to use that terminology. You're right, many here, on CF, and society in general, need to get their heads outta somewhere, and be mature enough to admit when they're wrong. Isn't my first mistake and wont be my last. But then, some just NEVER make any mistakes. Like all the people in cemeteries. They'll never make another one. But everyone else here will, unless they're dead. Learning to admit you're wrong isn't hard, if you're mature and realistic. Has nothing to do with Scott or anyone else.
If you go into the dyno section you'll find Mamo head cars are posting 480rwh numbers, maybe slightly higher. I suspect most are probably dual duty cars with a steel flywheel and maybe dual valve springs.

on a 10 flat, stock internals, bolt-ons only, LS6, in a full weight C5 Z06. I'll never believe it. If I'm wrong, I'm wrong, but I seriously doubt it. See my post before this one. The only thing I apologized for was telling him he was full of it, and I AM sorry. But I'm not apologizing for anything else I said. There's also something to be said for ANYONE here who has the ***** to apologize for anything they've said or done, and admit it when they were wrong. I can't remember ever seeing too many apologies on here (there's certainly room for more, for sure!), and I'm not looking for credit because I did it. But I'm sure as Hell dont expect to be criticized, either. Or be questioned as to my motives. I guess some people cant realize it when they've done something, or said something, wrong. It's sometimes the right thing to do...... I hear what YOU are saying, but I don't think you're hearing ME. You're talking about H/C cars. I'm calling

I find it offensive when someone's tries to tell me their LS1 powered 346 is making as much power on 93 octane as the LSX427 I built which has 11.5:1 with a 243/251 camshaft with .66X .63X lift with LME ported Brodix BR7's Fast LSXr 102 intake, NW102, going through an RPM Level 6 T56 and an S60 with 4.10's. My car is 3,840 rw and I'm 240. The fastest its been at the track is 11.6 @ 125.4 mph and it had a horrible 60ft..Pretty impressive for a car with all the creature comforts and full 3" stainless steel exhaust.
I know there's more in it. I didn't gut my car, that's what the 99's for. Cars can go faster ET's with less power when they're LAF.

I would say the car just doesn't make **** for power for that mph, the track conditions sucked unless that was the best it averaged. If it's 4080 with you, then that equates to roughly 630 fwhp, so mid 500s whp which is probably believable with that setup.
At 3200lbs and 130 mph trap speed, only 550 fwhp is needed. So 450-470whp in a c5 with some mild weight reduction (easy to do as my Z06 with minimal weight taken out was 3040 with half a tank, without me and a full 15lb nitrous bottle).
RW is with you in the car and as I stated the car didn't hook due to no burnout and not enough RPM on the launch. If I spray it she'll go 10's for sure those rings were opened up just for that purpose but now I'm thinking to hell with NA power lets do a piston swap upgrade the fuel system and go ProCharger

If it came across as me being a jerk that was not my intention. Every damn time I've gone into the water box for the burnout I forget to hit that stupid ASR button. I'm gonna disable that SOB!
Remember the good old days when SLP sold the module that made the traction control system default to off? Looks like there is one for sale currently on ebay.
I made the mistake of keeping traction control when I had the S60 built. I wonder if there's a way to disable it in the tune file? I suppose one way would be to just unplug the rear sensors.
So your car is 3840 with you? Or it's 4080 with you?

When I saw your post, I'm surprised you'd think any C5 weighs over 3,800lbs w/o a driver. They're not that heavy. At least, I've never seen it. 3,800lbs with a 240lb driver is probably right. My 2000 vert with an LS7 weighed an even 3,250lbs. With me in it (back then!!
), it weighed 3,430lbs......

10 flat 1/4 miles will instantly be ours. If that isn't quick enough, we could yank the LS6, and install a stock 5.3 and really kick ***!! I digress.......

Camaro, you and I are obviously going about this TOTALLY wrong. We need to pull our slow 427s, and install a stock internals LS6 and use every bolt-on available. Think how much our acceleration rate would improve!!!
