- There have been two versions of the 632ci big-block Chevy used in the Malibu since originally built. They both used an Edelbrock Performance intake, Air Flow Research heads, Dart Machinery block, Jesel rockers, and COMP Cams pushrods. Power is transferred through a Reid-case-equipped Powerglide, with a TCI Automotive flexplate and Coan Engineering 10-inch torque converter. They shift with a TCI Outlaw Shifter with Shifnoid solenoid.
The driving duties are now passed to Devin, and at a No Prep race, he ran a 5.05 e.t., spraying nitrous for the entire 1/8-mile. “Devin was able to feel the tires slipping while going down the track, but it went straight as an arrow,” Rob says. “He didn’t have to steer it or anything.”
Not only do the McGees compete at No-Prep events in their region, but they also go after the popular Outlaw 632 class that is held at many large heads-up events such as their first time at No Mercy 8 event last year. “We plan to spray a 250hp nitrous shot down the entire track at Eddyville, and we hope to get it into the 4.80s,” Rob says. “We will have to add 100 pounds to the car unless Devin lets me take the wheelie bars off the car. He’s a little gun shy of doing that because I flipped my old Monte Carlo over backward once.”
- Ultimately, they qualified number 17 at the big South Georgia Motorsports Park No Mercy 8 event in 2017 with a 4.84 e.t. That was the motivating factor in building a new 632 engine combination with more horsepower over last winter.
Driven to qualify higher in the Outlaw 632 category, the pair built a new 632ci big-block Chevy combination that dynoed in at 1,647 horsepower. “With the new engine, we started 2018 by running our best of a 4.82 in the 1/8-mile.” Rob then drops the bomb, “We were just starting to get the bugs worked out at the track when we received a purchase offer for the car that we couldn’t refuse.”
Rob and Devin are incredibly proud of the Malibu they built. What makes the story interesting is that they are primed and ready to dive into another banzai-build right away.
“We still have our new 632ci engine we recently built, as the car left as a roller. We are quickly making a decision about a sleeker body style to continue competing in the Outlaw 632 class,” Rob adds. “We are leaning towards a Cadillac CTS coupe if we can lock down a new body shell. Whatever we decide, the tubing is sitting here, and we are going to move forward quickly. I’m actually looking forward to some more late nights in the shop with my son.”Whatever body goes on the family chassis jig next, in just a few months you can count on the new ride being as slick as the first venture by the father and son.
