Drag Racer
Rob Leimenstoll races this fiberglass-bodied, big-block Chevy-powered ’48 Austin Nostalgia Gasser at Midwestern events like the Meltdown Drags and Gasser Nationals running a best of 8.20-164 mph. The 44-year-old Jackson, Michigan millwright began driving his father Bruce’s Sand Dragsters at 16, and eventually converted over to quarter-mile asphalt where he’s successfully been bracket racing for a number of years.

“About six years ago we found the Grape Ape ’48 Austin listed on Racingjunk.com. My father and I drove up to Cape Cod, Massachusetts. We liked what we saw, so we bought the car and brought it back home.” Leimenstoll told us.
Like many drag racing nostalgia cars, Leimenstoll’s Austin has a colorful history. Built in 1968, it’s one of six original Contemporary Fiberglass-bodied ’48 Austin two-door sedans built, and the only one released from Contemporary’s molds that wasn’t chopped. Named the Bushwhacker, it was state-of-the-art for its time (2×3-inch main rails, Summers-equipped Olds rearend, one-piece flip-front end), but it has almost no racing history to speak of. However, we suspect that this car may have belonged to AA/GS racer the late Keith “Bushwhacker” Bush, but this is purely conjecture.

Throughout the ’70s, the Bushwhacker changed hands a number of times. In 1979, or early 1980, East Coast drag racer Rocky Pirrone found the car through a specialty car wholesaler friend of his and traded it to fellow racer Joe Collins for a small-block Chevy-powered Open GT street car.
“Rocky only had the Austin for a couple of weeks, but never raced it,” Collins said. “In fact, it showed no signs of ever being an actual running car, there were no transmission or motor mounts; there was no nothing at all in that car. The paint job was really old. It looked as though someone had painted it and stuck it outside for about 10 years. I installed a small-block Chevy and Turbo 400 in it, repainted it Ford Probe Purple and rechristened the car the Grape Ape. We ran it in Super Gas and routinely ran 9.20s at 142. I remember I used to leave the starting line looking out the side window just to make sure I was going the right direction. Then when I hit high gear the front end settled down, and I was able to look through the front window and see down track!”

Collins kept the Austin for nearly 25 years. Around 2005, NHRA Division One racer John Lang purchased the Gasser, outfitting it with a single carbureted 427 big-block Chevy running in the low nines and continued to campaign the car as the Grape Ape.
“The car weighed 2,140 pounds. With that engine combination it was just barely legal for Super Gas,” Lang commented. “It was just a real, real light car.”
Lang campaigned the Grape Ape in S/G for about three years. Then he built up a blown, alcohol-burning big-block Chevrolet that he planned to install in the car but changed his mind, figuring that 1,800 hp was a bit too much for the short wheelbase flyweight and decided to sell it.
When the Leimenstolls purchased the Austin, they swapped in the same 427 L88 that they had been running 9.50s with in their Camaro and changed the Austin’s name to Attack. Leimenstoll’s father Bruce drove.

“When we bought the car, we had to update the chassis to certify it to run 8.50. We added a few bars to it and ran the car that way for three to four years. It was a really tight fit for me. I needed to be sitting farther back in the car, which meant that I would be sitting behind the rear hoop, so we sent the chassis to Randy King at Skinny Kids Race Cars to have a Funny Car cage installed. Once Randy got to looking into it, he called me up saying, ‘This is dangerous. You don’t want to have a crash in this thing!’ Randy showed me a lot of the things that they did back in the day that were quite acceptable, but totally different from what chassis builders are doing today.”

The Leimenstolls also purchased a blown 496-cid big-block Chevrolet engine from Waterford, Michigan’s Dare Devil Speed Shop. “We went a little overboard with the blown motor. Dad didn’t want to drive the car anymore, so that left it up to me. I made the decision to take the chassis all the way down to the main rails and start all over again, and this is the end result. It’s almost like having a whole new car, and now we can safely attack the sevens!”
