Hi aabad508,
I wrote a lot of books about this subject. Here is some info specific to your setup that I checked out on our procalc jetting calculator:
For 4400 foot elevation on a typical summer day with 83% air density, moderate enrichment on methanol, an 0.030" dia nozzle (nozzle diameter not nozzle number).
The main bypass depends on the size of the fuel pump,
independent of the proper nozzle.
For an 80A-0 at 4 GPM, a main of 0.077" dia is good for moderate enrichment.
For an 80A-1/2 at 5.2 GPM, a main of 0.099" dia is good for moderate enrichment.
For an 80A-1, at 7 GPM, a main of of o.125" dia is is good for moderate enrichment.
Small changes to nozzle or main bypass put the engine into a different setup and it may or may not run well.
Going to a different altitude may need different nozzles as well as a different main.
A smaller set of nozzles and main are needed for a high pressure setup that usually runs better. But that needs to be worked out with a high speed.
Introducing a high speed into the setup is complex. Recommend not starting out with a high speed until the car runs good without it. As stated above, you have to know what fuel pressure is at the RPM you want to open the high speed. That is 500 to 800 RPM above the torque peak, so you have to have an idea where the torque peak is.
Trial-and-error is tough on an NA engine. Too many things to coordinate.
