How to know if your b body 71 came with 120 mph or 150 mph gauge?
Mine are destroyed since the prev owner painted it.

A 383 4 speed roadrunner
With no rpm gauge, would it be a 120 then?

I am not sure how to tell, but my 71 Charger with 383 Magnum 727 has original 150 mph, my 71 parts car 383 2 barrel also had 150 mph.
I notice the 120 mph in a 74 Charger I had. I may have one in my parts if you are interested I can look.

120 miles Rallye speedos appeared in 73, although lot of 73, probably earliers, or probably HP cars still got 150 miles.

The only speedo in the '71 Rallye gauges was 150 mph. The standard speedo was 120. (I shoulda said standard dash)
