Question about A/F Rato Can someone give me ideal targets for an air fuel rato for a street driven head / cam car? Should the a/f remain constant across the rpm curve or get progressivey richer as the rpm increases? I'm a real know not on this and I would appreciate some basic spoon feeding.
My current dyno sheet shows I'm at 14.5 @ 2500 dropping to 13.0 @ 3200 and leveling out at 12.4 from 5000 - 6500.
How does this sound?

This was my dyno tuned LT1 motor, with a automatic (locked) so I got a low pull. It was a mail order tuned hot cam vs a larger emissions legal grind with dyno tune.
