House of Mouse Racing (HMR) has built several Hellcat-powered vehicles. We previously shared their Hellcat-powered Impala in 2023 and Hellcat-powered Coronet in 2020. Today we discuss their amazing 1970 Plymouth ‘Cuda.

 Under the carbon fiber hood sits a supercharged 6.2 L Hellcat V8 making 707 hp and 650 lb-ft of torque. Behind that is a Gearstar 4L85E four-speed automatic transmission using a CompuShift TCU. A carbon fiber driveshaft transmits torque to custom Moser rear end with a Truetrac limited-slip differential and 35-spline axles. 

 House of Mouse Racing upgraded the handling using Reilly MotorSports AlterKtion front suspension and Street-Lynx trangulated 4-link rear suspension. They also installed a USCT Motorsports weld-in chassis stiffening kit. The brake system consists of Wilwood six-piston calipers with 13-inch drilled and slotted rotors and an E-Stop electric emergency brake system. 

 The ‘Cuda body has an Elastomeric front bumper and SpeedKore carbon fiber hood and rear bumper. Everything is covered in PPG three-stage paint with a custom one-piece vinyl top. The front features an AAR grille and headlight bezel assembly while the rear has modified tinted taillights. The finishing touch is a set of Forgeline 3-piece wheels with Yokohama ADVAN Neova AD08 255/40 front tries and Mickey Thompson Sportsman S/R 31×18-inch rear tires. 

The interior features seats from a 2021 Challenger SRT Hellcat surrounded by a custom headliner, custom carpet, custom door panels, and custom lighting. A Billet Specialties steering wheel mounts on a custom Ididit steering column. There is also Dakota Digital gauges and a Vintage Air AC system. You can view more photos of the build and full specs at the project page.

What happens when you cross a big 70s sedan with 2020s Mopar Muscle? You get an autocross monster known as the “Mopala”.  It’s the brain-child of House of Mouse Racing Proprietor, Paul Terlosky of Twinsburg, OH. 

“I had a ’74 impala as my first car and raced it. It had quarter mile times in the thirteens.” He goes on to tell me that he specialized in Impalas for a while before getting into Mopars, specifically, Hellcats. “The last six years or so, I’ve done a lot of Hellcat cars and we had an engine and wiring harness laying around.”

The 1971 two-door Impala had become his “White Whale”. Because of a multitude of factors: UAW strikes, the Oil Embargo, the 1971 model year was a low-production year compared to 1970 or ’72 so the volume of two-door Impalas was limited. He was able to find one that had been a bit used up. 

“I wanted something to play with while my Cuda was being done and I had my sights set on competing in a Goodguys autocross event, but the only one left in the east was Columbus, so I had a timetable.” With only had 5 weeks to prepare the car for the event, he dropped the Hellcat engine from a Challenger it right into the ’71 Chevy. 

The old white interior was quickly replaced with blue leather and the suspension redone with QA1 coilovers with Wilwood disc brakes and a Gearstar 4L85E transmission. “I finished the car the night before we left for Columbus.”  And it workout well as he goes on to say, “I was out pro-touring F-bodies with this thing and no paddle shifters either!”  

Yeah, it’s a full-size Chevy but 707 HP sure helps. And if he ever needs service, all of the on-board computer systems still think it’s a Hellcat challenger, so he could literally take it to any Dodge/Chrysler/Jeep/Ram dealer.
