Builds

Off road racing in the desert Southwest has been around for almost forty years now and we’ve never gotten tired of looking at vehicles and hardware associated with going off-road. Off-roading–racing or just having fun presents problems. We’re always intrigued by some of the solutions.Here’s what we found on a recent trip to Baja.

Steering is one of the two most important systems on any vehicle, along with the brakes. Unfortunately, steering is often neglected for modifications that yield more visual impact, such as suspension lifts and larger tires. These are the exact modifications, however, that make attention to steering so important. Suspension lifts can alter steering geometry while big, heavy tires may cause increased wear to steering components, particularly if the tires are out of balance.
After a springover conversion was performed on the Dana 44 front axle in our ’67 Toyota Land Cruiser, the new spring location interfered with the steering geometry. The draglink was then bent as a temporary fix, but this sacrificed strength and resulted in poor steering angles.

In part nine of our Cimtex Rods Super Cameo Buildup Series, we covered the installation of the Classic Industries Parts and Accessories reproduction ’55-’59 Chevrolet/GMC lower door hinge panels, doorsill rocker panels, upper and lower door hinges, new right- and left-side front floor pans, inner and outer lower cab patch panels, and right- and left-side truck cab supports. To put it in a nutshell, the crew at Cimtex Rods in Jarrell, Texas, basically rebuilt the whole bottom end of our Super Cameo ’56 Chevrolet big window truck cab from stem to stern. Now, with a rock-solid truck cab firmly bolted onto our Cameo’s highly modified C4 Corvette-suspended truck chassis, we closed with the promise that we would be installing a new set of Dynacorn International Inc. ’55-’59 Chevrolet/GMC reproduction truck doors, followed by angle-chopping the top on our ’56 big-window a total of 3-1/2 inches in the front and 3 inches in the rear. Unfortunately, things didn’t exactly go according to plan.

In part seven of our Cimtex Rods Super Cameo Buildup series, we covered the installation of our Stainless Works four-tube ZR1 headers and Cimtex Rods-fabricated 3-inch custom exhaust system, as well as the fabrication and installation of our Cimtex Rods-constructed 22-gallon fuel tank and the accompanying MagnaFuel fuel system. Now we’re going to cover the mockup of our Powerdyne BD-11A SilentDrive twin supercharger system. But first let’s digress and take a look at the big picture. One of the key criterion in our Cimtex Rods Super Cameo buildup was to elicit that all-important “wow” factor throughout the entire series. When it came to the engine, we didn’t want to install just any old run-of-the-mill, multi-carbureted GM small or big block, much less a late-model GM crate engine straight out of the catalog. Going in we figured that the Cimtex Super Cameo powerplant should be something special.

“What’s going on right now with this truck is probably one of the most difficult parts of the overall buildup,” commented Cimtex Rods’ Darrell Cimbanin. “Getting everything to fit inside and underneath this highly modified 1956 Chevrolet Cameo half-ton chassis, like the exhaust and fuel systems, for example, requires a lot of thought and careful planning, not to mention the actual fabrication process, which is very time consuming!”

In parts two and three of The Auto Builder’s Cimtex Super Cameo series, we followed along as Cimtex Rods primaries Tim and Darrell Cimbanin instatlled one of Flat Out Engineering’s Corvette C4/C5 front and rear independent suspension crossmember kits beneath a 1956 Chevrolet 1/2-ton pickup chassis.
Of course, this was followed by the actual installation of the 1984-1987 Corvette C4 rack-and-pinion-steering-equipped IFS and the bolting up of the 1984-1987 Corvette C4 IRS, which makes for a pretty nice-handling street truck.
Along the way, some modifications to the Corvette C4 front suspension were made for the sake of simplicity and an enhanced ride. For openers, Flat Out Engineering designed its kit to incorporate a pair of 12-1/2-inch Aldan Eagle 659/450 coilover shock absorbers, which replace the somewhat antiquated GM designed Owens Corning Corvette C4 monoleaf fiberglass front spring.

In Part III of our Cimtex Super Cameo buildup, we’re going to follow along as the guys from the Jarrell, Texas, crew modify the rear framerails on this ’56, “kicking it up” a full 8 inches. In the process, Tim and Darrell will also narrow the Corvette C4 IRS half shafts to achieve the much desired rear tire clearance they need in order to be able to run a set of humongous 20×10 billet wheels wrapped with a set of BFGoodrich radial T/A rubber.

“Building a good truck chassis is just like building the foundation for a house,” says Cimtex Rods’ Tim Cimbanin. “Everything starts at the ground floor. If you don’t have a good foundation, you don’t have anything!”
No truer words were ever spoken, and we’ve been preaching this fundamental information in all our publications.

While attending the 2003 SEMA Show, we ran across Darrel and Tim Cimbanin from Cimtex Rods in Jarrell, Texas. The Cimbanin brothers were there to drum up support and showed us some sketches of their latest truck building project, and what a project it is!

The lines of ’55-’57 Chevys are almost sacrosanct. They haven’t been modified or changed over the years with very good results. There have been a couple of exceptions, but by and large, chopped tops, restyled fenders and other modifications that alter their original lines don’t come off looking real good. The problem is in the proportions. We’re not sure if it’s because the factory got them so perfect right out of the gate, or if it’s that most have been left alone over the last 50 years, so a chopped top looks strange. Whatever the reason, the classic “greenhouse” roofline, long fenders and slab sides all work very well together.
