Don't bet on Mopar fanatics not hearing the name. If you were into drag racing in the late 70s as I was, the Hamburger name was very familiar. As KB and Ed Pink were to Hemis, Hamburger was to smallblocks.
Hamburger now does mainly GM and Ford stuff. He is involved with SLP

My father is doing well.
He sold the Mopar business in the early 80's to concentrate on Hamburger's Oil Pans which in turn was sold to fully concentrate on SLP.
Since '91 we've built over 55,000 vehicles for GM including all of the 1996-2002 Camaro SS, '91-'02 Pontiac Firehawks and many other GM Performance Niche vehicles. He's still running the day to day business at SLP and enjoying every minute of it.
