Week to Wicked: Day Two…It’s What’s Under The Hood That Really Counts

End of Day Two of our Week to Wicked presented by Classic Performance Products and we are on the verge of having a running hard and super driving C10 made from an ugly duckling C20. (Apologies to all of those C20 fansI got carried away!).

We've taken a longbed long wheelbase "pickemup" and turned it into the rage of the day with a Brothers bed shortening kit, CPP front and rear suspension and braking, and an updated fuel system from Holley. Now the fun starts.

28 CPP Week To Wicked Day Two Mast Ls7 Performance Automatic 4l80e 2/41

We are looking at dropping in the MAST Motorsports 427ci Chevy engine that we have dyno'ed and walked away with 702 hp and 600-plus lb-ft of torque. It's based on a LS7 (7L) motor will be breathing through a FAST LSXrt truck intake manifold equipped with a 102mm Big Mouth billet throttle body controlled by a FAST XFI Sportsman ECU and fed via Holley fuel pump mounted in the relocated CPP gas tank and routed using Earl's plumbing hardware. Controlling the spark will be handled by a FAST EZ LS coil-near-plug controller mated to a set of L92 truck coils. With all the modern conveniences required, we'll be relying on an Eddie Motorsports S-Drive kit to spin all the necessary accessories on the front of the engine. To ensure the big inch LS stays nice and cool, an aluminum Frostbite radiator equipped with electric fans will regulate the under hood temps.

4180e Driveshaft 3/41

Transferring the power to the pavement will be accomplished via Performance Automatic Street Smart Series 4L80E. A bulletproof combination, the LS drivetrain should provide plenty of power and be as reliable as a brand new truck.

The last step today was to check exhaust fitment and also measure for a driveshaft. Remember that this truck originally had a two-piece driveshaft but now it will be a considerably shorter one-piece conventional driveshaft. The exhaust will be based on a Holley system beginning with Hooker coated exhaust manifolds and then run through Hooker Turbo mufflers.
