For you, you'll be doing a dyno pull, then to change your timing curve you'll pull the distributor, change out springs, put it back in and set timing. To change fuel you're pulling the top off the carb, changing jets, putting the top back on, all while your paying for dyno time.

I'd dial in the fuel by making a WOT run through the gears, shutting down to coast to a stop and reading the plugs. Check around the old mechanics shops and find one that has a distributor machine and you're done - https://horsepowersports.com/distrib...ke-a-comeback/

I hope you'll come back and let us know what you find when you get into the engine. 36 sedan gave you two good old school rules to follow....

I guess I should elaborate, I was going to do as much "tuning" as I could on the street before taking it to a dyno. My tuner guy does 75 dollars for 2 runs, and I want to do it just for my own satisfaction to know how much power I'm making, (expecting 500 crank). He won't even touch the carb, so no worries about paying for that.

I have an AFR gauge installed in the car, and if I can find someone with this distributor machine like you're talking about, I feel like I should be able to get fairly close to max power.

I'll echo Rogers comments above, use the money for a good timing light instead.

Here's a link to an article I wrote for my car club a while back that will show you how to adjust and set your timing;
