Default C5 Heads /Cam Full Bolt on Dyno

Just picked my 2001 M6 convertible up from Exotic Performance Plus in Columbia City Indiana today. Need to say that Bob & Brent were very professional, communicated very well and did a great job on my Heads/Cam install. Now for the details:

Stock bottom end
Lingenfelter heads with Patriot Golds
Ed Curtis Flowtech Cam 224 228 .612 .612 112+3
Ported Fast 90
Ported LS2 Throttle Body
LG Street Long Tubes Headers- no cats
ATI 25% underdrive pulley
Vararam intake
LS2 Timing chain
Melling oil Pump
160 degree stat
MSD Spark Plud Wires
Fidanza Aluminum Flywheel
Fidanza 3.2 Kevlar clutch


Car put down 434 RWHP & 419TQ on their Mustang Dyno. It's my undestanding Mustang Dynos are 7-10% stingy so this would equate to between 465 & 477 RWHP on a dynojet. I have a shop locally with a Dynojet and will probably take it there soon just to see the difference.
Here is the dyno sheet from EPP:

Killer TQ curve. I like that 224/228 grind, produces great results & driveability.

On a dynojet you'll do around 460rwhp. Not bad at all for a GM casting and sub-230 duration cam

I would be very interested in seeing the Dynojet comparison. I have been thinking of doing the same myself.
