“Tubbing Black Beauty” – Wayne Robinson’s 1965 Chevelle

Any drag racer will tell you, “Consistency wins races”. When Wayne Robinson began racing his ultra clean 65 Chevelle, it wasn’t long before he realized that traction with the high powered Big Block Chevrolet powerplant was an issue, and that the much needed “consistency” was a problem. Here is Wayne’s Chevelle before any modifications:

The “first generation Chevelle” was very limited on space for tires and the traction they provide. The 64-65 Chevelle in stock form can only fit around an 8-9” wide rear drag slicks. Which are easily overpowered by even a mild big block like the one in Wayne’s Chevelle.

Limited traction made it hard to “dial” the car and tire spin was a common occurrence. Wayne made the decision to install a narrowed rear frame, a 9” Ford Rear End Housing and ultra wide rear slicks to solve the “traction issue”.  The plan was to include an 8 Point Roll Cage for safety.

Wayne chose Ron Pircey Enterprises to do the conversion as Ron is well versed in the installation process and uses only the best components. The first step is to remove the old rear suspension and related components.

The rear trunk area was then cut to accommodate the Art Morrison Narrowed 4-Link Rear Clip. The clip is then welded into position. These photos show the rear clip tacked in place along with the Main Hoop of the new 8 Point Roll Cage. The cage is made from 1 5/8 DOM tubing in accordance with NHRA requirements.

The cage is attached to both the rear clip and braced to the stock frame as well. The extra strength provided by the roll cage and bracing will prevent any flexing that was common with the non-reinforced stock chassis.

Once the paint was dry, construction continued with the installation of the wider wheel tubs and rear tinwork.

Additional tin work in the center portion of the trunk and some assorted small tin pieces were fabricated to finish the flooring in the trunk area.

A Valiant Effort

With the racing season now in full swing, and racers as a general rule upgrading their race cars every off season… It stands to reason that along with more power, a better convertor or the myriad of other upgrades that make your car faster; a roll bar or cage is not only safer but may be required!

Darryl Hendrickson and his daughter Megan own a beautiful pearl white 68 Plymouth Valiant.

That now runs in the 10’s and was in need of a roll cage. Besides what father wouldn’t want his daughter to have the safest possible race car?

Darryl enlisted Ron at Ron Pircey Enterprises to install an 8 Point Roll Cage that was custom bent from 1 5/8” X .120 wall DOM Tubing to meet the NHRA requirements. After the measurements were taken and double checked, the afore mentioned tubing was bent to fit closely in the Valiant. As the following photos will attest.

The first step in the installation process is to form 6”X6”X1/8” plates at every location that mounts to the floor.

There are NHRA required reinforcements to the Main Hoop of the Roll Cage that provide additional support. Again, the 6”X6”X1/8” plates are used to spread the load where the supports attach to the floor.

Note the tight fit of the Roll Cage Main Hoop and Roof Line Bars that follow the contour of the headliner in the door openings.

The Eyebrow Bar also fits tightly in the area above the windshield and connects to the corners of the Roof Line Bars at each end of the windshield.

Once everything is tack welded in place and checked for final fit, the finish welding completes the job. Darryl Hendrickson can rest assured that his daughter can be both safe, secure and legal now that the roll cage is complete.

Ron Pircey has 100s of dimensions cataloged to install a roll bar or roll cage in a variety of vehicles. If you’re working on an unusual project then it is simple to take the required measurements so he can install one for you…..
