Talking GMMG Dale Earnhardt Intimidator SS with a Vengeance 383 and a D-1SC

Many people may not know that Ron Mowen, owner of Vengeance Racing, and Mike Carnahan, owner of Vengeance PCM, actually started their LS careers at GMMG. So, some 10 years later, when the chance to work on a GMMG Dale Earnhardt Intimidator SS came around, we were more than happy to have the Camaro roll into the shop.

Unfortunately, the Intimidator SS rolled in with a cracked #7 piston...

But, that just meant we we got to put the Vengeance Racing twist on the GMMG car and we took power from a rated 381 to a verified and dyno proven 630-rwhp!

Vengeance Racing 383ci LS1
Callies 4-inch Crankshaft
Callies 6.125-inch Connecting Rods
Wiseco Forged Pistons
Calico Coated Main/Rod Bearings
ARP Main Studs

Vengeance Racing Custom Camshaft
VR Dual Spring Kit
Comp Cams Lifters
Comp Cams Trunion Upgrade Kit
Melling Oil Pump
Katech C5R Chain
ARP Head Bolts
ARP Cam Bolts
All new Gaskets and Seals

Power Adder:
ProCharger D1SC System with 8 Rib belt drive
ProCharger Horizontal Mount Race Intercoolers

RPS Street Twin Carbon Clutch
New GM Slave

Our customer specified that the Intimidator needed to make over 600-rwhp with a 383 and a ProCharger... We were quite pleased to see the combo belt out 630.86-rwhp and 595.96 lb-ft of torque!
