Hello I’m new here. Just removed the throttle body EFI and coil pack from 1995 196 SNOB with 5.8 PCM 351 Ford. Replaced it with electronic distributor and Holley 4160 with vacuum secondary 600 CFM. Just curious if anyone has any experience regarding the primary and secondary jet sizes used to get the best results. Without a air/fuel ratio gauge it’s a bit trial and error using only manifold vacuum readings. I also have all of the old EFI components except the ECM.

First...welcome.
I did a very similar conversion on my 1994 Ski Nautique. The throttle-body EFI and ProTec engine management system were both failing. So, I removed all associated equipment and went "old school" with a carburetor and distributor. The retro motor ran as strong as it ever did with the EFI and electronic wizardry. I have a lot of info for you regarding your 4160 carb and associated conversion work. Check your Private Messages ("Messages" can be found at the top of the page).

I went back to my notes when I converted my 1994 Pro Boss throttle-body EFI and ProTec to carb and distributor. This is what I had:
Carb settings
Primary Main Jets 71 / Secondary Jets 78 (sea level)
Primary Main Jets 69 / Secondary Jets 76 (4,500 feet elevation)
High Speed Air Bleed 31
Idle Air Bleed 70
Pump Nozzle 33
Power Valve 6.5
