Air Fuel Ratio - General best target to shoot for

Cazbah362 said
I installed a FiTech Go 4 600 on to my 470 - 5 speed car. It runs good, just need to provide the best tune as practical for the fuel map. I have the system managing the timing so, need to balance that out. Meaning it is locked out and computer manages the "at idle" and the curve for the "all in" which goes at 2000 to about 38* right now.

The engine is a 470 440 source kit, about 10.4, with large valve 452's, small roller cam (540 lift - can get the @50 if necessary), T2, TTI's headers and FiTech - also, I live at 5400 feet and run 100 pump gas. I like to do some spirited driving, cruising, autox, and drags (mostly cruising and spirited driving)

Question is - what AFR have you learned is the best for this scenario/setup? Yes I can go with 12.5 to 13.6 but from what I read Mopars like closer to 13.2 - what can you share from practical application, and what would you recommend?

Thanks in advance

Mine is a small block but I run it in the low to mid 15's at idle and light cruise, and in the mid 13's when into the secondaries under load with a grand total with everything including vac advance in at light throttle (2,500-3,000) RPMs is 52 degrees advance.
The thing is, you can adjust for the numbers like you posted but it's going to vary a bit while running anyway.
This probably doesn't help you much overall, but that is what I run.
I get 25+mpg at 80 mph with the overdrive and 350-400hp

Outside of the general AFR numbers I posted, yours would probably serve best tuned on a dyno if you want to get it at it's very best in all conditions.
