The new Hemi engine has been the last chapter of the build for Frank, and he enjoys taking it out on the roads any chance he gets. "I built the car to drive and cruise and I do just that," he says. It may have taken him a long time to finally settle down and build the car of his dreams, but he has proven it was worth the wait. He built the car for himself, the way he wanted to build it, and he couldn't be happier. Who wouldn't want to cruise around town in a '70 Challenger with a Hemi and giant blower?

Fast Facts

1970 Dodge Challenger R/T
Owned by: Frank Maynard
Arvada, Colorado

Mopar Power

  • Engine: Sadly, the level of under hood attrition has been rather high for Frank. When he originally completed the car it had a 440, which he scattered a few times before looking into another form of propulsion. The new engine would be none other than the infamous Hemi with 426 cubic inches of hunger being fed by a 6-71 Weiand Dyer's Supercharger. The appetite for destruction is fended off with a set of 8.5:1 forged Keith Black pistons, Mopar I-Beam rods, and a forged steel Mopar crankshaft. A set of Mopar Performance aluminum heads were then bolted on which feature 2.25-inch intake and 1.94-inch exhaust valves. The assembled heads are given a workout by the Isky .524/.507 248/248 camshaft that opens the valves via 1.7 intake and 1.65 Mopar roller rockers. A pair of Holley 750 Double Pumper carburetors feed the whining Dyer's Blower from Weiand, which has a custom butterfly snorkel to gobble up cool, outside air. The oiling system has remained stock with a stock pan. A set of TTI 2 1/4-inch primary headers merges into 3.5-inch collectors draining into a 3-inch Flowmaster exhaust. Frank performed all engine work and assembly.
  • Transmission: A stock 833 with a pistol grip shifter and Mopar clutch. Frank says it doesn't hold the power too well, but he figures that will keep him from breaking more down the line.
  • Rearend: An 8 3/4-inch rearend features an aluminum center section with 3.55 gears and an original Sure Grip differential.

Sure Grip

  • Suspension: Since Frank wanted to get the car a more menacing look he wanted to drop it. He removed roughly 2-inches of ride height with a pair of drop spindles and rear Super Stock springs. Everything else on the car was left stock.
  • Brakes: Stock front discs and rear drums.
  • Wheels and Tires: Coy's C-5 wheels give this Challenger a look-at-me flash without being too gaudy. They measure 18x8 front and 20x9 rear with 245/40R18 and 275/35R20 BFGoodrich tires.

High Impact

  • Paint/Body: To the best of Frank's knowledge, the body was all original aside from the front right fender which was replaced before he purchased the car. He performed all of the bodywork to bring the car as close to perfect as humanly possible and he then sprayed it with Scarlet Red paint.
  • Interior: Inside the Challenger there were some small changes made. First, the bench seat was removed because Frank wanted to go with buckets and a console. He sent his dash pad off to Ultimate Ride to have them expertly restore it while his gauges were sent down to Florida to have them rebuilt.
