Hi guys. I [picked up a beautiful 1971 Eldorado convertible that originally came out of TX , it was in Grand Junction but i doubt it was ever re-jetted for elevation. I am at 5,000 feet here in SLC, UT so i bet she is running a little rich right ? Any body know what jets shold be in it? It is the 500 and I assume all stock carb. prob a 4brl rochester , do you guys change jets often ?
