During the chassis build, the best sheetmetal from each truck was assembled and restored to stock specs before almost every piece of the truck would go under the knife so the Roadster Shop could perfect what Henry started all those years ago. Some of the first matters at hand were to move the wheel opening of the new steel Pro's Pick fenders forward to match the new axle centerline, pie-cut the stock hood 1 1/2 inches to help relieve the '53 of its nose-heavy silhouette, and angle-chop the top 1 inch at the front. It doesn't sound like much, but it helped clean up the truck's clunky stock profile.
The build would soon take a turn for the intricate as it progressed with more and more scratchbuilt components, like the handformed floating aluminum grille and Hagan headlights in custom-frenched buckets affixed to perforated steel. All this is recessed in the grille area just above the heavily modified C2 Corvette front bumpers and PIA fog lights that mount in a custom roll pan.
Most every corner on the cab was rounded, the cowl vents were filled, the handles and emblems were shaved, the seams were welded and smoothed, and the doors were cut and modified for one-piece side glass. The Roadster Shop even made custom running boards to ensure that they flowed properly into the front and rear fenders and were raised up from their stock location to, again, perfect proportions. The rear fenders were widened 1 1/2 inches in a pie-shaped fashion to add more depth to the rear sides to ensure the wheel openings were parallel to the wheels as they sit in the fenders. The Pro's Pick bed was massaged and tailored to match the rest of the all but one-off truck, which includes the noticeable tailgate changes and, of course, the unique and intricate aluminum-framed, vacuum-formed, carbon-fiber bed floor insert crafted by 3G Services in Taylor, Michigan, because wood simply wouldn't do at this stage. Also in the F-100's rear are heavily massaged C3 Corvette bumpers that now hold Watson's StreetWorks LEDs.
After all this work, it just wouldn't be right to stick a plain Jane motor into the '53, so a call was made to Mr. go-fast himself, Bill Mitchell, to place an order for one of his World Class 509ci big-block Chevy motors that thumps to the tune of 560 horsepower. To get all those ponies to the BFGoodrich G-Force tires out back, a Tremec TKO-600 five-speed transmission was ordered from Keisler Engineering and nestled between the framerails. Dressing up the inwardly brutish Rat motor are a set of Billet Specialties valve covers painted and striped at the shop, and preceding the big-block is a Billet Specialties Tru Trac serpentine belt system to keep things spinning in unison. The Roadster Shop fabricated the 3-inch stainless steel exhaust that incorporates Flowmaster 40 Series mufflers and mates up to the Sanderson Big Tube headers.
