Chaplin,
I think 2.5s are too low for what we discussed. Try 5.0s, with the jets, air filter, discharge nozzles we discussed. Also, my throttle butterflies are drilled too, with the secondary slightly cracked open.

Also, be sure your fuel pressure is not too high. Critical. Do you have an electric fuel pump and regulator? The needle valves will blow off if you get over 6.5 lbs on some Holley's; especially if the needle valves have not been replaced in a while/dry, etc. We just took my friend Marc's car from 7.0lbs at the gauge/regulator down to 6.0 and wallah! His rich mixture problem is gone.

Let me know how it goes.
