Afr on 250 alky blower
Just wondering on what y’all seeing as a reading on your boosted alky setups .
I’m seeing 4.8 on my setup . Cut open spark plug and seen good maybey even bit on rich side .

I’m running a 41 top and 67 bottom getting about 2.8 lbs of boost 31 degree right out of the hole ,430 gears big bubbas ,runs 4.53 @ 153 mph in good air . Dragster weighs 2080 lbs with me in it .
