and Nate at Blitz Creed, we upgraded our lug pattern to 6 on 6 1/2 and a new TubeWorks housing. We ran hard and heavy with 2 spares and 75 gallons of fuel. TrailReady made the wheels custom for my truck, they held up great with no issues. Beefing up the drive train and developing a wheel with TrailReady Wheels in such a short time frame, from when we saw the opportunity to run the new Development Tire, took a lot of work. The Drive train package with the 42' Tires is the Ticket! My co-driver, RJ just keeps saying WOW!Ĭlearance the truck for the massive 42' tire was easy. We had to call it quits at180 miles but for those miles we were ruling the desert. With the old 3.90:1 gears, Marc's 3,700-pound car ripped off a best quarter-mile of 11.44.The 42' BFG Tires were awesome. South Bay Driveline made him a custom driveshaft (that passes through a Marc-built driveshaft safety loop) to transfer torque to the 10-bolt (3.42:1 gears, Eaton differential, and Moser axleshafts) that was once beneath a WS6 Firebird. Transmission fluid courses through a Flex-A-Lite cooler. Though he aims to feature an overdriven 700-R4 to bring his car in compliance with the Pro Touring shtick, Marc currently runs a manual shift Turbo 350 and a 10-inch B&M Holeshot converter with a 3,200-rpm stall speed. On the pump, the big little-block produced 503.5 hp at 5,900 rpm and 496.6 lb-ft of grunt at 4,450 rpm. Though rarely invoked, Marc's got a button for the NOS Super Power Shot juice system worthy of 100-150 hp. High voltage rips from an MSD 6A box gases resultant are sucked away by Hooker Super Comp headers measuring 17/8x30 inches. Fuel is atomized by a 750-cfm Race Demon carburetor and dispersed through the tunnels of an Edelbrock Victor Jr.

A Moroso sump, windage tray, and pump do the oiling and return via a Chevy truck oil cooler. Pushrod guides, retainers, and locks are Trick Flow items. Complementary equipment includes Comp valvesprings, pushrods, and 1.6:1 roller rocker arms. A semi-bumpy stick was in their thoughts, too, a Comp Cams flat tappet XE284H-10 hydraulic sporting 240/246 degrees duration at 0.050 and a lift of 0.507/0.510-inch. A Scat nodular iron crankshaft and Scat forged rods hold up the bottom end. Keith Black hypereutectic pistons with Total Seal ring packs squeeze up a compression ratio of 10.35:1 with Trick Flow Super 23 195 CNC-profiled combustion chambers holding 2.02/1.60 valves.

The plan was moderation big displacement for a vivid low-end and just enough stick to let it breathe well on the top.

McCool and Marc did the build after Performance Products in Phoenix, completed the necessary block work and balancing the rotating assembly. That fabled 350 ci swelled up like a sow's belly, displacing a sumptuous 406 ci.
