Rain Couldn’t Damp the Enthusiasm of Nearly 400 Drag Racers at the 2018 Meltdown Drags

After we flew five hours from Los Angeles to Chicago, news of a weather front moving through the Great Lakes Region wasn’t what we wanted to hear. Pressing forward up I-90 in afternoon traffic towards Byron, Illinois, to attend the Ninth Annual Meltdown Drags, our thoughts were with past Meltdown events and how much fun we’d had covering them. In today’s structured world of motorsports, the Meltdown Drags are something of a rarity. No eliminators, no record runs or qualifying brackets, no huge cash payouts or trophies. And above all, no whining. The basic premise is just go out there, be safe, and have fun!

Sanctioned by Vintage Drag Racing 101 and manned by such dedicated Midwestern gasser enthusiasts as Eric and Jeff Koopmeiners, Paul Zielsdorf, Art Zangerle, Tom Bucek, Steve Liberto, and “Smokey Moe” Petersen, the Meltdown Drags also features a car show, a swap meet, and Gasser Alley, where you may run across a vintage gasser or altered on display from the bygone era. Heck, there is even a pinup-girl contest, won this year by Cassandra Hicks.

The event also attracts its share of luminaries from back in the day, including featured guests Ed “the Cam Father” Iskenderian and gasser great Robert “Bones” Balogh, along with former Funny Car stars Arnie “Farmer” Beswick, Hawaiian and Chi-Town Hustler driver Ron Colson, Randy “Super Nova” Walls, ex-Ramchargers Top Fuel driver Merek Cherktow, and fuel altered star Gabby Bleeker.

This year, 390-plus entrants who braved the weather represented groups like the Scott Rods AA/Gassers, Great Lakes Gassers, Brew City Gassers, Nostalgia Gasser Racing Association, Southern Outlaw Gassers, Northern Indiana Gassers, Geezer Gassers, Southeast Gassers, Southern Gassers, Mid American Willys Club, Straight Axle Mafia, Twisted Pistons, Tin Butchers, Nostalgia Super Stocks, Border Bandits, Gopher State Timing Association, No Car Club, and others. Talk about a slice of vintage drag racing Americana!

Strip promoter and track owner B.J. Vangsness and his crew had to fight 3 inches of rain on Friday repeatedly prepping the track a whopping 12 times, but they were not to be deterred. As for the racing itself, it became necessary to shorten the measured distance from a quarter to an eighth of a mile on both Friday and Saturday for safety reasons (racing late into both nights). But none of the 10,374 spectators (which included visitors from Sweden, Australia, and Great Britain) seemed to mind, as the actual show itself was on the starting line. Then with a dry track surface, quarter-mile racing resumed on Sunday.

Meltdown 2018 was a rousing success in spite of Old Man Weather. If you like what you see here, start making plans to attend the 10th anniversary edition of the Meltdown Drags July 19-21, 2019.

On the Back Bumper The unofficial wheelstander award went to Don Moyer and his 401 AMC–powered, (that’s right) Rebel Reaper fiberglass B/Gas 1941 Willys coupe. He pulled bumper-dragging wheelies on every run.

(Not) the Pits Come hell or (almost literally) high water, the Meltdown Drags pits were bustling with activity throughout the weekend. More than 390 competitors participated in front of a record attendance of 10,374 spectators.

Off-Track Action The swap meet and car show areas at Meltdown 2018 also had plenty for the fans to see and buy.

Past Gas Minnesotan John Zechbauer rolled up with the restored Lutz & Lundberg 1941 Willys B/Gasser. This was L&L’s breakout car. In the early to mid 1960s, the famed gasser team also raced Anglias and a very weird and wonderful altered-wheelbase Oldsmobile Funny Car named 442 Much.

First Out Winnipeg, Manitoba, Canada’s Gary Misko with his red 1937 Willys Americar two-door sedan, and the Long’s Garage 1967 SS396 El Camino, were the first ones down the track during Friday’s rain-delayed eighth-mile drag racing.

Living Legends For the third year in a row, special celebrity guests Ed Iskenderian (left) and Robert “Bones” Balogh signed autographs and sold drag racing memorabilia including hats, T-shirts, and posters.

Twisted Deuce Meltdown fans loved the starting-line gyrations of Gold Chain, the 1932 Ford C/Gasser belonging to Midland, Michigan’s Dave Gray. The coupe, powered by a small-block Chevy engine, ran in the low 10s.

Tailwind This is what it looks like when you are trying to do a respectable burnout with the wind at your back. The event director of Meltdown Drags, Paul Zielsdorf, took a little time out on Sunday to lay down a 10.46/129.00 run.

Off the Map Meltdown Drags board member and all round good guy “Smokey Moe” Petersen poses with some of the European visitors who routinely attend the event.

Street Driven Ex-Ramchargers Top Fuel driver Merek Cherktow warms up the tires on his street-legal, two-seat blown Chevrolet/Bantam. The car is capable of low 8s, although Cherktow struggled with the rain-washed track surface.

Big Beats Small Mark Benjamin, driving the Benjamin, Kasicki & Klink AA/GS 1933 Willys with blown small-block Chevy power, took on Scott Rods’ Al Borowski in a big-block Anglia. This particular heat was won by Borowski, recording a 5.62-second eighth-mile e.t.

Up, Up, and Away Muscle car collector Jim Paulson wheeled the ex–Candies & Hughes-Jake’s Speed Shop altered-wheelbase 1965 Plymouth Savoy past Wally Petersen and his 572-inch AWB 1965 Hemi Dodge Coronet. Paulson ran a best of 10.50/123.00, but since Petersen didn’t file a flight plan with the tower, no times were recorded!

Wheels-Up Chevy David Tanner’s blown small-block, chop-top 1932 AA/G Chevrolet coupe has been a regular at the Meltdown Drags. His wheels-up runs are always popular with the fans.

The Future These two small fries appear to be poised and ready to jump into Junior Dragsters and get with the program. Someday, dad, someday!

Wheelstand Battle The anticipated side-by-side wheelstand showdown between two of the Midwest’s Tri-5 wheelie kings, ex-Chicago police officer Mike Bilina and “Iron Man” Tony Shervino, failed to fully materialize. Timing between the two racers appeared to be the problem because it sure as heck wasn’t the cars.

Classical Gassers Nostalgia Gassers’ Steve Bacon and his Innocent Rascal 1941 Willys B/Gasser squared off against the Lost Wages 1956 Chevrolet B/Gasser of Robbie Roberson in a match that Bacon won.

Ford vs. Chevy Tommy Killingworth’s Miss Fit, a 1963 Ford Fairlane AA/GS running out of the Southern Outlaw Gassers group on pure Ford power, faced Randy Stone’s Bootlegger A/Gas 1955 Chevrolet shoebox, which won this particular heat.

Colson Stude Pitside attractions at Meltdown 2018 included the former Colson & Wood/Scott Hammack AA/Gas 1941 Studebaker coupe. A Pennzoil ad from the March 1963 HOT ROD, which was displayed with the car, extolled back-to-back class records: 11.64/118.42 at Oswego, Illinois, followed by 11.33/131.78 at Cordova. At the wheel was Ron Colson, who also earned fame driving the Chicago Patrol, Hawaiian, and Chi-Town Hustler Funny Car (among others).

Stead(y) vs. Crazy Marty Stead driving the Stead Speed Shop 1941 AA/Gas Willys went off against fellow Scott Rods circuit member Brian Spotts and It’s Crazy, his 1952 AA/G Anglia. Running on a 5.60 index, Stead posted a winning. 5.64 seconds in the eighth-mile.

Black Magic Check out Alex Case’s street-driven 1965 Dodge Coronet. It is powered by a Keith Black alloy Hemi with Stage V twin-plug Hemi heads, twin magnetos, a Danekas blower, and eight (count ’em!) Stromberg carburetors. Unbelievable!

Missing a Few Another oddity to be found in the Gasser Wars display was this blown Chevrolet Hemi V6. We’re not sure about the who, what, or why, but the pintsize Hemi sure drew a lot of attention.

Holeshot In round one of the Scott Rods show, Mike Kalinowski’s Un-Finished Business AA/Gas ’52 Austin took on Jeff Cryan and his wheelstanding 1933 AA/G Willys known as the Phenomenon. Can you guess who won?

Burnin’ and Churnin’ Nostalgia Super Stocks member John Grinwald and his Gold Digger 1965 AWB Dodge put on one heck of a show for Meltdown Drags fans Saturday with eighth-mile smoky burnouts.

Street-Legal Sprint Car Street-Legal Sprint Car: How many times have you seen an old Kurtis sprint car running around town? Well, if you live in the State of Illinois, you might run across this Ford flathead-engined single seater.

Dueling Hemis The ever popular two-car fuel duel: Jim Henry’s Big Iron injected nitro Hemi-powered 1964 Plymouth and Steve Moth’s Bad News 1964-1965 AWB nitro Hemi Dodge traded wins throughout the weekend.

Beating the Bully Rich Maier and his Blacktop Bully 1940 Chevrolet C/Gasser went up against the Mr. Quick’s Speed Shop–sponsored Moon Dust 1965 AWB Plymouth. The Hemi won.

Ultravintage Floyd Craig’s 21-stud, flat-motor-powered D/Altered Model A and Kevin Croise’s similarly powered Ornery Buzzard front-engine dragster are regulars at the Meltdown Drags and underscore the meaning of dragstalgia.

Free Booty A popular feature with Meltdown Drags participants is the prize booth. The racers’ ticket numbers are randomly drawn throughout the event, and they are allowed to select from a bevy of really cool items.

Sincerest Form Paul Brown decided that since he already owned a replica of Doug Thorley’s Chevy 2 Much, why not replicate the former Burgeois & Wade Doug’s Headers Logghe Chassis flip-top Corvair? A close inspection reveals that the car is expertly done, borrowing visual cues from both the B&W car and Thorley’s U.S. National–winning Corvair. Yes, there were two. That’s car owner Brown in the fire suit.

Chip off the Old Block Following in his dad Paul’s footsteps, 17-year-old David Zielsdorf jumped behind the wheel of the family’s 427 big-block 1963 Chevrolet Biscayne on Sunday and hammered out a 12.06/116.00, topping the old man’s personal best by a couple thousandths of a second.

Hot Track Seven-year-old Oliver Bucek mans the Mattel Hot Wheels race track, where every kid who participated got to choose and take home his own Mattel Hot Wheels die-cast miniature.

Broke as Hell According to the shoe polish on the windshield, the “world’s fastest outhouse” Model A runs in the 10s thanks to a 371-inch “Chevy/Olds” V8. Rick Neal’s Possum Killer Garage built the roadster pickup, which now belongs to T.K., Tug, Bo, and Trouble Thompson of the Broke as Hell Garage of Memphis.

Henry Battle Nostalgia Gassers member Tom Peter’s Drag Addict B/Gas 1951 Henry J went up against Nick Nampa’s No Quarter 1951 Henry J B/Gasser. Nampa took the win.

Quicker Than the Auto Club Whenever one of the contestants lost fire, the Meltdown Drags starting line crew was quick to remedy the situation.
