Mopar gassers?

It's a line drawn in the sand. Most of the old straight axle coupes with blown and injected Hemis were always considered Gassers regardless of what fuel they burned. If we use "Gasser" as a generic term describing the look, Any car with a straight axle front end jacked way up and some fat tires on the back could be considered a gasser.

I have to disagree somewhat. The original idea of gas was a "street car" which was modified. Altereds were never considered to be a streetable car For me, that IS THE defining line. That is, having a bad *** car which can actually go down the road, regardless of how bad the fuel mileage was. Running a supercharger does NOT kick you out of "gas" it just put you into "/GS"

Gassers (at least originally) had to have some sembelance of stock seating position, IE no rear seat or center steering, had to have wipers, lights, and even if a tiny single exhaust, had to have a full exhaust system. When gas was first created, cars even had to carry license plates. These rules were changed as things went along, and I see NHRA by 62 had dropped some of this "street stuff."

Altereds had none of this, allowing more engine setback, center steering, etc.
