What's the correct pulley size for the AC compressor on a 1970 454?
An internet search shows 5" and 5 3/4" are possibilities. I also see reference to 5 1/8", 5 1/4", 6" diameter pulleys. I suspect there are two diameters produced, and the other measurements are due to how it's measured. But I'm not sure.
The diameter of my current pulley is 5 1/4", measured outside lip to outside lip. It's just a bit larger than the hub. The larger pulley I sometimes see on cars (aka 5 3/4") is visibly larger than the hub.
Has anyone seen a listing of which cars used the larger diameter? High red line engines?
Nothing found with a search on this forum or the shop manuals.
