More new 416 dyno numbers. 573/530rw N/A!!! I am helping a friend of mine with some tuning so we used my car on his dyno today as a guine pig. I ended up putting down 573/530rw N/A SAE and 587/543rw UCSAE. Not bad for a daily driven 416. I only note the uncorrected numbers because that is what the car is actually seeing that day on the street. The car felt like a monster today on the street. Hopefully Kurtomac will chime in. He got a ride before I went to the dyno. With better air this thing might crack 600rw N/A uncorrected. I guess these numbers back up my track times the other day. I didn't change any thing from my last dyno session except the clutch wasn't slipping at all this time and I really fine tuned my timing tables. I don't think I messed with the fuel. The weather was comperable to last dyno and the correction factor was the same. I still need to get an EWP and cut out's. Here are the graphs.

my jaw hurts (no homo) from the grin i had on my face during the ride....rolling on et streets kicks it in 3rd gear at 60mph (4000rpm) blows the tires off....wacks 4th and spins them all the way through 4th....slicks were clawing for traction....speedo was climbing like a bitch and I knew that thing was making some big power...
Pray-thanks alot for the help today....we found that I wasnt even at zero lash (about .010 shy of zero lash so with the .040 of preload i need with the 850 16 comp lifters I need a 7.550 pushrod, wipe looked good....btw thanks Ron at VR as well for hookin me up and getting those pushrods out today....hopefully with the correct length pushrod, we can squeeze out another 15rwhp between having correct preload/taking advantage of my cams lift and duration, and tweeking the tune some more...maybe this sunday I can head back that way and we can strap my car on the dyno and see what she does
Again thanks Pray and badass ride

Badass Bret. Your Vette is a monster. Look forward to seeing 140 mph trap speeds in cooler weather!

Thanks guys.
Smokn: The 92 is the standard ported one that comes from Vengance. I am running a home ported LS2 TB. Ron did port match it for the 235's for me.
98 Camaro: The SCR is 12.0:1 and the DCR is 8.5:1. I run 93 octane all day in the south. I have found a good bit of power reducing the timing to a point I was sure I would loose power. I am not very smart. These heads are awesome.

Don. Looking at the power band and my combo, is there any way to gain some more up top? This thing is pretty much peaking at 5,900 and flattening out till 6,500 and falls off hard. I am assuming that is intake, possibly exhaust related? I am in no way dissapointed (the numbers are actually hard for me to believe and I did them) and I don't want to give up any thing down low. I just really though this motor would keep climbing to 6,500 or so.
