Guy’s Speedtech Built ’68 Chevelle on

“When it arrived at Speedtech for work, it was clear that the paint and engine were already squared away, but the suspension was in dire need of replacement. The build team made it all better with a new Track Time A-Body suspension kit, comprised of new upper and lower control arms up front, upper and lower trailing arms out back, and QA1 adjustable shocks on all fours. Also included was a new Currie Enterprises 12-bolt rearend, Wilwood brakes, and new wheels and tires.

Now capable of handling long-duration drives, Simkins was primed and ready to test everything out as he drove over 700 miles from St. George, Utah to his hometown in Hamilton, Montana. “One of the main reasons Guy built the car was to take it back home [to Montana] for a big burnout contest there. The car wasn’t even totally finished when he loaded it up and took off for the event this past summer! He even bought a second set of wheels and tires specifically for the purpose of burning rubber.”

“Prior work done to the Chevelle’s Speedtech upgrades included its powertrain, constituting a Mark IV 454ci BBC V8 that had been bored .030 over and stroked to 4.25-inches for a total of 496 cubic-inches of displacement, and packed to the brim with aftermarket support from Edelbrock, MSD, and COMP Cams among others.”

“It can run on pump gas and still make 608 horsepower and 622 pound-feet of torque,” said Simkins. “Just a total beast.” The big-block Chevy was fitted to a Turbo 400 with a 3,900 RPM stall converter, controlled inside by the stock shifter and console.”
