Ok ive got a map for a 727 with a single and all other mods are the same. How much should i lean it out to get close
Bore size should not effect the map... compression will, but I believe if you did a 9.2:1 727 it would use the same map as a 686. ???
Sorry, i should have been more specific on what i was asking. I did get it figured out though

SD, I'm confused. A larger bore will require a larger total volume of fuel/air mixture to run correctly. The larger piston will be drawing a larger volume of air into the cylinder and so the FI map will need adjustment to meet the ~12.7 to 1 A/F ratio. I would think a SB map would be very lean??
And I also thought that compression should do very little to map requirements, since the A/F requirements would not increase or decrease?

That is correct. If you displace more air, you need more fuel. And compression should not affect your map.
You are correct Clorado... I smoked alot of weed in my day. LOL I guess my brain was slow when I posted that. OOPS! :clap: I will say the 12.7 should be 13.1.... :P
