They don't have injectors. If you mean jets, V8 are bigger (like Dodge 318)

Stock main metering jets on a '76 258 are 120-389. I can't find a high-altitude listing right now, but you want a leaner jet as the air is less dense. Maybe only one or two steps, but you'll have to read plugs or get a wide-band sensor to do it properly.

Hope that helps.
