Ram Jet

Did GM ever install the Ram Jet on anything besides Chevy? Would any other division of GM call it something else?

Perhaps I'm using the wrong name. By the late 50's Chevy had a fuel injection system that looked like a big box on top of the 283 Bel Air or on the 327 Corvette. I seem to remember the Pontiac Chieftain had available fuel injection and I was wondering if it was the same?

heres the late 1950s-early 60s corvette injection, it was functional, but hardly easy to keep precisely tuned, the ports and runners restricted power on larger engines so it was best used on a 327 displacement or smaller and I had far better results with properly tunned tunnel rams and cross ram intakes like the SY1 and OFFANHAUSER DUAL QUADS

Ive played with several over the years and they flat SUCK compared to a properly tuned modern MPFI system or even a tunnel ram thats properly set up and tuned, and don,t produce near the power or have the looks of tune-ability of a good stack injection.

I had FAR BETTER RESULTS WITH A CROWER STACK mechanical INJECTION

but the more modern MPFI injection with computer controls and sensors is far more precise and is FAR IMPROVED over what the early mechanical injection in the early vettes could do.

when chevy went racing with the grand sport corvettes they used weber carbs not MECHANICAL INJECTION
