The Hurst Barricuda "Hemi Under Glass" was A Rolling Research Laboratory. It said so, right on the door. The idea was to move the Hemi engine over the rear wheels to improve traction but the result was immediate wheel standers at every launch.
Yesterday, I couldn't remember where I had seen the understated but wicked fast gold and black color combination. I thought it was from a Trans-Am era BOSS Mustang, but while driving on the freeway, I remembered it was the Hemi Under Glass.
