But then again, not many SD455s really had 455s, and then again
again the Ram Air IV that they used in place of the missing 455s was actually a more powerful mill taken all around- it breathed better

My 74 Camaro with a 350V8 had 145HP and a unrestricted top speed of 115.
My 76 Malibu with a 305V8 had 120HP and couldn't break 100 MPH.
Then things improved, my 79 Camaro had a 305V8 with 140HP and had a top speed of 120MPH.

True, but I was doing it in the '90s so I just removed the emissions stuff and put in block off plates. Trouble was the awful manifolds, small valves and low compression. But the day I yanked the emissions stuff off the '74 455 (rated about 230 hp) engine I transplanted into my '70 Skylark was the first day I spun the tires in third gear- with an automatic.
The disgusting thing was that you could find some Buick, Olds, or Poncho 455s with a factory
2 barrel carb! Ug.
