Dallas Glenn must be living right.

His day job is crewing for three-time NHRA Pro Stock champion Jason Line at KB Racing. His personal race car is a 1968 Chevy El Camino given to him by his grandma. And he got to build a new big-block bullet for the Elky with assistance from Mr. Line himself.

Glenn grew up in a racing family, starting in quarter-midgets at age five. But the drag racing bug bit hard thanks to his grandfather, Don, who bracket raced a ’55 Chevy wagon. When he turned 17 in 2008, Glenn took the El Camino to the track for the first time. In a sign of things to come, he won his first of nine NHRA Wallys that weekend.

He finished in the Top Four that first season, and won the Sportsman title in the Race of Champions run during the NHRA Division 6 Summit Racing Series Finals. You can read more about Glenn’s racing career in the ‘Dallas Glenn Chasing Win Lights’ story.

Despite a crazy schedule during race season, Glenn drove the El Camino every chance he could. He figures the car has made 1,500 to 2,000 passes down the track from 2008 to 2017, running a best of 11.90 at 112 MPH.  Here are the specs for the car and the original 427:


• All-steel body except fiberglass cowl hood

• Factory suspension and brakes

• Turbo 400 transmission and stock 12-bolt rear end with 3.90 gears

• Factory bench seat interior with AutoMeter gauges and MSD ignition box

• Weight: 3,750 lbs. with driver

• 28 x 10.5 rear tires


• 427 cubic inch big block Chevy, estimated 450 horsepower

• Stock 454 engine block with 4.280” bore

• Factory forged 396 crankshaft, Eagle I-beam rods, SRP forged pistons

• .590” lift solid roller camshaft

• 396 oval port iron heads

• 750 CFM 4150-style carburetor on Edelbrock dual plane intake manifold

But like any good racer, Glenn wanted to turn the wick up. That meant building a new, badder 427. Glenn and Jason Line put their heads together and came up with a list of parts:

• Factory 454 iron block

• Eagle 4340 forged crankshaft and H-beam rods

• SRP forged dome pistons

• Isky solid roller camshaft, 290° duration, .622” lift

• Factory 396 oval port iron heads with bowl cleanup and PAC Racing valve springs

• Holley Ultra XP 850 CFM carburetor on an Edelbrock Performer RPM Air-Gap intake

“My goal was to make more horsepower so I could add at least 150 lbs. to the rear of the car. That will help it hook better and be more consistent,” Glenn explained. “The new engine would be about 50 lbs. lighter, so I could move that weight to the back of the car. I figured around 500 horsepower would be enough to run 11.50s in the quarter-mile, even with the added weight.”

Glenn got his wish, and then some. Tuned on the KB Racing dyno, the 427 made 537 peak horsepower at 6,000 RPM and 517 lbs.-ft. of peak torque at 4,600 RPM. And that is about as much power as Glenn wants, and for a very good reason.

“I don’t want to go any quicker because then I would have to add a roll bar or cage,” Glenn continued. “Doing that would mean making permanent modifications, which I just can’t do to Grandma’s car.”
