The ideal A/F ratio is the one that makes the most power, either on the dyno, or at the drag strip (MPH)...........It can be anywhere from 10.9 to 1 to somewhere in the mid 13's.........and it all boils down to fuel fall out.......How good the fuel distribution of the intake is and how fast the air speed is through the port........

What's your motor build up??? What heads?



I have a 340 punched .060 over, cylinder pressure
is 190 psi cranking, running stock heads, eddy
air gap rpm manifold, and eddy performer rpm cam.
Carb is a street avenger 670. Running a pertronix
ignition but thinking about a msd box.

The car feels light under wot at 13.5-14 but was
thinking it might make more power set richer.
It does feel more labored running down at 10.5 or
so.
