Nope, they had Muncies. I sold a 74 Muncie M21 that came out of a Camaro years ago.

My first car was a 76 Sport Coupe with 305. Eventually became 400 small block and then 402 big block. When I repainted it IROC Firemist (the red that had the gold pearl in it) and painted the aluminum bumpers body color it really cleaned up the lines of the car. That's the way the 77 Z's were done and I really like that look over the natural aluminum bumpers.

Earlier 74's had muncie and points. mid year they switch to HEI and B&W T-10
