We only ran across one Caddy drag car.
It was at the div 4 bracket finals race, which was held at the old Green Valley track, in either '77 or '78.
It was long & red. Besides being a drag car, what I thought was interesting was that it was a 2-door. I didn't remember seeing many 2-door Cads, before that.
It was powered by a 500 inch Caddy engine. I think it had two 4's on it. Not positive. I remember thinking that a 500 Cad engine should have lots of torque. IIRC, that Cad ran mid 11's.
From lookin at some online pics, it had to be a '69 model because of the tail lights. So, I suppose it was a '69 2-door Coupe DeVille. Didn't find any pics of a red one. But I'll post 3 pics of a black one. Wish we'd have taken a pic of the red drag Caddy back then.
Never saw an old Caddy running Stock or SS. Just looked up the '69 Caddy. It shows a 375hp 472 engine, but no specs are listed. I know the 472 had plenty of torque. In '73, I pulled my GTO to the tracks with a '68 model 472 powered 4-door Caddy, & tow bar. No power problems at all.
It did use quite a bit of gas. I drove it from North Louisiana to the NHRA Finals race in Amarillo, in '73. There was a gas shortage of some sort. Lots of stations were either out, or only operated a few hours per day. Thought I was gonna have to stop & wait for daylight, when the stations opened. But, I finally came to a big all-night truck stop that had plenty of gas. I won't charge ya'll for that little glimpse of history.
