How high is the compression on your 250? The only thing I'm curious about is the Quadra-jet. To my knowledge, the smallest available was a 725cfm. Granted the primaries are small, but the secondaries are huge. Just curious. I'm using a rejetted 600 cfm edlebrock on my almost stock 250, and it doesn't seem to be running rich. Just my 2 cents.
