Question: What's purple, street-legal, licensed by the state of Wisconsin, and runs 8.52 at 159.5 mph on 93-octane pump gasoline?
Answer: Craig Shefchik's blown big-block '66 Chevelle Malibu!
Multi-faceted Craig Shefchik is renowned as one of the best paint and bodymen in the greater Green Bay area, and he is also rapidly becoming known as a master street and race car fabricator in his own right.
Of course, it only stands to reason that Craig practices what he preaches. And his recently completed '66 Chevelle Malibu is certainly proof of that.
Constructed at Craig's Luxenburg, Wisconsin-based shop, Shefchik Auto Body and Race Car Chassis, the Chevelle features a Shefchik-fabricated 16-point rollcage and back half constructed out of 4130 chromoly tubing. Attached to that is a Shefchik Race Car Chassis Pro Four Link-AFCO coilover shock rear suspension setup bolted to a 4.86:1 Strange Engineering-geared Miltner Brothers/Fab-9 Ford rear axle housing equipped with a set of Moser 36-spline rear axles and Aerospace Components rear disc brakes.
Front suspension on Craig's Chevelle consists of Global West upper and lower tubular unequal-length control arms along with a pair of 2-inch Belltech dropped front spindles, HAL QA1 coilover shocks, and Strange Engineering front disc brakes. Steering is handled via a Flaming River rack-and-pinion steering rack attached to a Shefchik-fabricated steering column. Also on board is a custom-fabricated Shefchik fuel cell housed in an aluminum trunk enclosure along with dual Optima batteries and a Pro Star fuel pump.
Wheels and tires on Craig's Chevelle come in the form of 15x5.5-inch front and 15x15-inch rear Aluma Star wheels rolling on 26x4.5x15 and 33x22x15.5-inch Hoosier rubber front and rear.
Credit for the machining and co-assembly of that outrageous 572-cid Donovan aluminum big-block Chevrolet goes to Neenah, Wisconsin's, Competition Specialists. Internally, the big-block utilizes a Lunati cross-drilled forged-steel blower crank, a set of Clevite engine bearings, Oliver H-beam connecting rods outfitted with ARP cap-screw rod bolts, and a set of Total Seal-equipped 8.5:1-compression JE forged-aluminum pistons. The cam of choice is a Crower. Cam timing is set via a Jesel beltdrive, and lubrication duties are handled by a Tilton oil pump and a 7.5-quart Jeff's Billet oil pan. Also on board is a CSI electric water pump. The heads are Goodwin Competition-prepared Brodix BB-III's outfitted with a 2.30-inch Manley stainless-steel intake and 1.92-inch Manley stainless-steel exhaust valves along with a Donovan stud kit and Crower and Manton valvetrain hardware.
Bolted up top is a Mert Littlefield 14.71 blower pumping 13 pounds of boost using an Enderle Bird Catcher scoop. The engine management system on Craig's Chevelle is from the folks at Fuel Air Spark Technologies (F.A.S.T.), while ignition duties are handled by MSD and NGK. A set of 2 3/8 to 2 1/2-inch Shefchik Race Car headers and Dyno Max 5-inch performance mufflers handle the exhaust. Backing this up is a Transmission Specialties Incorporated TH400 featuring a Cheetah shifter and valvebody. The final link in the '66's powertrain is a Jerry Bickel Race Cars custom-fabricated driveshaft.
Craig lightened up the Chevelle's body with a set of Glass Tech fiberglass front fenders. The Chevelle (painted in PPG Global Purple with clearcoat) runs hoodless in order to show off that awesome big-block and trick Shefchik Race Cars interior aluminum. The Chevelle also features a neat rear deck wing (partially concealing a Simpson parachute) attached to the removable one-piece rear deck lid.
Inside, Craig's '66 features even more trick aluminum panel work painted silver and purple. The car uses a set of lightweight Cobra bucket seats, a custom dash containing an array of Auto Meter instruments, and Simpson Safety Equipment.
Weighing in at 3,350 pounds, Shefchik's Chevelle has clocked a best of 8.81-152.00 at Wisconsin International Raceway (a.k.a. Kaukauna Drag Way), and has won numerous awards at Street-driven events. In closing, Craig would like to thank his friend Glen Perleberg, his wife Sandy, and his sons Alex, Jordan, and Logan for all their help and support in building this truly awesome machine.
