I started with the Edelbrock that came on the car and if fate had sent me something else like a Holly I would have dug into that. My passion is tuning, making whatever it is run as well as it can, including jets skis, power tools, and model airplane engines!
Edelbrock Tuning
I few years ago I worked through the process of tuning an Edelbrock Performer Series AFB with an O2 sensor taking notes along the way. I have a decent write up on the topic with all of the areas I worked on including: Initial Setup, Timing, Dist Recurve, Carb Tuning, Etc. and am thinking about making a post. One of the pieces to the puzzle is an interactive expanded Edelbrock Tuning Chart showing every possible rod and jet combination. Excel versions of these already exist in the wild, but this one is interactive. My question is if anyone is interested in this or is this old news everyone already knows about? Here is a peek showing the details of a particular rod and jet combination. Note that the rods are represented by the lines and the jets are the symbols on the chart with the color representing options for a particular jet in that area:

Thanks for the reply, yes I agree that simple instructions are needed. Since the conversation is started here is another piece of the puzzle showing an MSD distributor recurve calculator. The approach here is to determine the best spring and bushing combination to use in a mechanical distributor given the available tuning options. So instead of measuring the distributor on something like a Sun 600 machine just pick the best fit given all of the options given initial and final values.

Explanations pending, but the chart above shows the springs that are needed with the red lines. So in summary I am attempting to create a few visual tools to help with tuning. I just updated the screen shot to show the results.Likewise for the springs, some simplified help as to why 14°, why 28°, and why at 2400 rpm? This is the missing-link info users really need.
