One of our favorite episodes of the popular show PassTime on the Speed Channel was Randy Jackson “misleading” the panel with his 1988 Mustang GT. He said it was mostly stock with just a C4 and 175-horse dry kit, but then he busted off an 8.72 at 165 mph. He totally played off the fact the Mustang had way more than what it appeared. That’s the grudge life; not giving away any secrets, and keeping everything close to your chest.

This is 598-cubic inches of hurt feelings on two kits.

Recently, we learned of his latest grudge project; this 1984 Monte Carlo SS known as the G-Thang. Jackson, or ‘10.5’ as he is known on many drag racing message boards, says he takes the car to shows, but we don’t believe him when he says that’s all he does with the car. After all, we have photographic proof that it’s gone down Maryland International Raceway…well, at least once.

We weren’t born yesterday so we know the car’s primary goal in life is to get down the track as fast possible. Jackson tells us the engine is a conventional-headed 598-inch big block Chevy made up of a Dart block, Race Flow Development-ported Edelbrock Victor heads, a solid roller cam, a Reher-Morrison 4500 intake, a Pro Systems SV-1 carb, and two direct port nitrous systems. A Power Grid with an ARC module makes everything play nice, while a Dedenbear case Powerglide sits in the tunnel. Out back is a Ford 9-inch with 3.70 gears.

This is Jackson’s former Mustang grudge car. YouTube it, we’ll wait. Actually, we won’t, we have work to do.

The fender-exit headers and front end fabrication was handled by Todd Dobson of Mod Rods in Macon, Ga., while the cage work was done by Francis Johnson at Fast by Francis in Mechanicsville, Md., where Jackson currently resides. To enable the car to cut 1.17 60-ft times, Brian Anderson of Anderfab in Warner Robins, Ga. set-up the rear using Varishock struts and shocks. The front clip is from VFN fiberglass, and Jackson says the hood is the 1st six-inch cowl hood VFN made for a Monte Carlo.

“Thanks to Showtime Racing for all the help and Jeffery Barker for all the safety items and assistance that he has provided,” Jackson says. He tells us the Monte Carlo has run as quick as 4.74 at 152 mph on 28’s. Should we believe him?
