For years, the Preston name was associated with LSX Real Street racing, as Adam Preston successfully campaigned Camaros in the class for several years. This year, Adam and his brother Isaac debuted a new 1969 Camaro that was built to go really fast, as in Mickey Thompson Radial Wars fast.

Powering the F-body is an updated version of the big-block Chevy that was under the hood of the brothers’ previous Fourth-Gen Camaro. Bischoff Engine Service put together the 540ci rat motor that is now boosted via a pair of Precision Turbo Gen 2 94mm turbochargers and as Isaac explained, the combination has been maintenance-free. With an RPM Transmissions two-speed Turbo 400 and PTC torque converter behind it, the drivetrain is sure to be a capable performer. The car is was also rebuilt from the chassis up, as it was purchased as a wreck and needed just about everything, including a 25.2 chassis certification for the big speed and ETs it would soon see.

The Prestons debuted the Camaro at the NMRA/NMCA All-Star race in Atlanta in early 2017 with Isaac taking over the driving duties and posting big numbers right out of the trailer. The Prestons qualified in third with a 3.96 effort at 197 mph, and posted a 4.05 and a 3.97 to win the first two rounds of eliminations—this was with 88mm turbos and the car weighing 200 lbs overweight. With a pair of 94s and at the correct weight, the car was poised to post some impressive numbers.

In Bowling Green, though, a slight wheelie problem experienced in Atlanta became a big problem at Beech Bend Raceway Park.

“We went testing at Ohio Valley the week of Bowling Green and had really good success,” Isaac told us. “The car was basically a rocket ship. We went to Bowling Green and threw more power at it, but the shocks were bottoming out. I pulled a bunch of power out of it, but it still went up in the air. At that night session, it went 1.06 to the 60, and it was 3-4 boost numbers higher than the 3.96—it was on a low 3.90 pass,” Isaac told us excitedly.

The Caneyville, Kentucky, resident said that they have been changing a lot of stuff around to get the car to improve on the front half of the track.

“We think we have the issue figured out and plan to test before Joliet,” Isaac said. “We need to slow it [the suspension travel] down and lengthen the four link. We only have 32 hits on the car since we brought it out, and I think it needs another 20 to figure things out.” With a handful of 3.9-second timeslips already, it’ll be exciting to see what the Preston’s beautiful ’69 Camaro can do once it’s “figured out!”
