501 HP / 460 TQ......."Cam Only" LS3 (PIC's and VIDEO)
FINAL (SAE) DYNO RESULTS ARE IN...501.0 RWHP / 459.7 RWTQ
My factory baseline #'s were...
388HP
392TQ
"Cam Only"...meaning 100% factory block and untouched LS3 heads w/ supporting mods (headers/intake/tune)
I purchased a brand new 2010 Corvette a few weeks ago and dropped it off w/ John@21st Century Muscle Cars in Dallas to have the following parts installed...
2010 LS3 Corvette MN6 w/ 500 miles
-21st Century CMC-30 cam 227/239 .629 .623 114LSA
(idle set@700rpm)
-LG Superpro 1 3/4"" headers (no cats)
-B&B bullets for 3" exhaust
-ATI 10% UD pulley
-LSXr 102mm intake (hasn't been ported)
-Nick Williams 102mm billet throttle body
-Halltech Superbee 102mm air intake
-Comp 921 spring kit, titanium retainers, harden seats
-Comp 7.4" harden pushrods
-Cloyes timing chain
-160* thermostat
-Hurst Billet shifter
-dyno tuned by Matt Garzonie
I chose to use 21st Century Muscle Cars based on the quality of work and attention to detail on my last 2006 C6 Magnacharged car.
21st Century CMC-30 cam (proprietary grind by Comp Cams for 21st)
227XER /239XER 114
intake .629 lift
exhaust .623 lift
VIDEOS............
VIDEOs are worth a thousand words on here! Here you go, cruising around 1000-1400rpm's at 30-40mph:thumbs:

I've been a registered forum member here for almost 10 years and have used MTI/HPE/LG/Speed Demon/RPM/21st Century on the last half dozen cars I've owned and have seen many vendors/sponsors come and go over the years. I don't really keep up with who is in the "in crowd" this week.....so I'm not here w/ an agenda, but I do give credit when credit is due. Hope every one understands.

I assume you're talking about the 2008 GMC Yukon Denali 421AWHP on 24's, L92, all motor LS HOT CAM, KOOKS...that's impressive #'s considering AWD on 24's! But I was thinking the GM hot cam was fairly tame, being 219/228 .525 112LSA ? What made you decide to go with a GM aftermarket cam over the others?

Nice writeup with good looking work. It is unfortunate there is so much politics, backstabbing, and jealousy on this forum. It leads to lots of misinformation. Are forum members lives so empty and meaningless that all they can do is talk s---t about someones hard work and good fortune. Besides dyno numbers are as honest as head flow numbers and the people publishing them.

No plans right now, I rarely had time to drive my other blown LS2 car that was built for me last year....I did a write up on that one a while back too.

You are correct that 500 rwhp is very nice..I was not saying that there was anything wrong with his numbers .... just pointing out that folks had been putting down higher numbers without spending the $$ for a FAST and a aftermarket TB ... getting the most bang for your buck is what a lot of folks on here are looking for ... there are many shops and some are better than others obviously...it is really pretty EZ to get to 500 with the LS3 compared to the LS1,LS2, and LS6

There are some LS3s vettes running around at 500 RWHP + without touching the heads, but the majority of cammed LS3 vettes are not going over 490 RWHP without a pretty big bumpstick. Even some of the "stock heads" LS3s over 500 RWHP had a thinner gasket or flycut the pistons to allow for proper PTV.
