Mr. Norm's 1968 Hemi Dart for 2007

The 1968 Hemi Dart was among the most notorious muscle cars ever sold in the Americas. Its 426 Hemi engine and light weight made it the car to beat, on the street or strip.

Only a few were built in 1968; in 2007, "Mr. Norm" created a few more. Each car had a build book, production sheet, and build order, and was delivered by Mr. Norm himself, just as in 1968. The total remained under the original production run.

Mr. Norm has also created the prototype 383 Dart GTS and the M-Code 440 Dart, both of which were later put into production by Chrysler; and sold the majority of the legendary Hurst/Campbell-built 1968 Hemi Darts.

Built using 21st century parts and accessories, the GSS Hemi Dart should have better performance than the original, but it's based on the older cars. Mr. Norm brought original 1968 Darts into the shop, dismantled them, and examined each part to see whether it could be restored or needs replacement. When no parts were available, parts were hand-made with metals of the same alloy and weight. Restoration and build-up were handled by Blue Moon Motorsports.

The body shell was cleaned to bare metal on a rotisserie, and water treated with a rust inhibitor. Metal fabricators corrected original imperfections in the sheet metal by using hand dollies; any replacement parts were spot-welded at the factory seams. Mr. Norm's wrote that no fillers are used; instead, the metal was hand contoured to the original shape. Any epoxy primer started the painting process.

The body was hand sanded and primed three times. After a final wet sanding by hand, the body was painted in sealer, base paint, intermediate tinted clear, and final clear coats. The body was baked at 150 degrees for thirty minutes to cure the surface, and then allowed to air dry for 48 hours.

Two days later, the body was removed from the paint booth and wet sanded by hand with 2000 grit paper; then buffed.

The car then gained its new, stroked 426 Hemi™ dual quad engine, the driveline, upgraded suspension, brakes, and cooling systems, and related systems, with new wiring, plumbing, and restored gauges. The interior was sound and heat insulated; it gained a new headliner, dash pad, and auxiliary gauges, with five point seat restraints. Suspension components were preloaded and adjusted before road testing.

The GSS Hemi engine began with a new Chrysler 426 Hemi block - iron or 356-T6 aluminum - with a standard bore, hot tanked and magnufluxed. Rotating assembly components were billet steel, forged aluminum, or tool steel. These engines ran on pump gas, and were sold in 472 cubic inch and 528 cubic inch forms.

Bowler Performance Transmissions set up the 727 Torqueflite automatic or the A833 4-speed.

The Dana 60 was the mainstay of all Mopar muscle cars sporting the Max Wedge and Hemi powertrains; it was rugged, easy to build, and could accommodate just about any gear and posi combination. Mr. Norm's used new nodular units that were tougher than the originals, with 4.10 gears.

To minimize body twisting, Mr. Norm's GSS Hemi Darts used custom sub-frame connectors from Control Freak Suspensions. To accommodate the massive 285/40-17 Pirelli P-Zero ultra performance tires, the rear wheel houses were enlarged by three inches, and the stock spring mounts were relocated to stronger torque boxes made by Blue Moon Motorsports.

Mr. Norm demanded that the front suspension system use upper and lower control arms with coil over performance shocks. The whole K-member had to be crafted from Drawn Over Mandrel (DOM) seamless tube. The new front suspension system eliminated torsion bars, and used rack and pinion steering.

In the rear, leaf springs were changed to a split monoleaf spring supported by fully adjustable traction bars to change the pushing point on the car and help weight shift towards the rear while maintaining the correct pinion angle, eliminating any bind.

Prices for a GSS 1968 Hemi Dart in good condition ranged to nearly a half million dollars in 2007; the new 2007s sold by Mr Norm's started at $149,000, lower than many clone cars.
