Googled a couple of things......

"HEMI used 12-bolt GM ring/pinon gears as opposed to Ford style gears traditionally used by Halibrand, Winters, et.al. Other than that they used the same 'change-gears' as the others. The main problem (as far as Sprint/Champ car applications) was weight: they were appreciably heavier than traditional Halibrand/Winters Q-C's. They were fairly recent(late '80's- early '90's ?) so bearings & gears should be readily available, & they are certainly strong enough. If you have a 'stock car/modified' unit with a differental & axle housings you're in good shape: if you've got a solid axle(open wheel) unit you've got some searching /fabrication/conversion chores ahead. I see in your picture that you have an 'open-wheel' version: you'll need to adapt/fabricate axle housings( possibly use a 12-bolt rear axle for donor parts?) & add a differential for the street."

HEMI stands for Harrison Engineering and Marine improvements. It was owned by a good friend of mine by the name of Bill Harrison. His brother's name was Dean Thompson a driver from the LA area. The full size HEMI quick change used DANA 70 gear sets, not GM 12 bolt gears. He also built a Midget quick change that was smaller. I reduced the midget down and make a 1/4 scale quick change.

The main problem with the full sized HEMI rearend was that it used Hypoid gears not straight spiral bevel gears. In a quick change the gearset gets flipped over and the driveshaft goes under the pinion. Being Hypoid the pinion gear moves up in the housing causing the driveline to move up in the car. This caused a problem in sprint cars of the driveline tube wanting to hit the seat.
