Just remember that all specifications like timing and jetting are given at sea level. Didn't care when I lived on the east coast at elevation of 375 feet. Didn't even know it was an issue.
Now living at 4500 feet, it makes a difference. Thinner air. Timing and suggested jetting might need to take elevation into consideration.
Computer cars adjust automatically. Some of our older trucks don't. (Mine's a 73.)
I'm going to set timing a couple of degrees higher and adjust from there. Never had an adjustable vacuum timing advance before. That's going to take some messing with also.
Gonna start with jetting that came with Eddy 1406 and adjust from there.
Trying to maximize performance with what I got. Not adding and new major parts.
