Have a 440 with:
10:25 compression
Pocket ported heads
Comp cam XE274 cam
headers to 2 1/2 exhaust with flowmasters
727 auto with 2400 stall and trans-go shift kit
3.23:1 posi rear end
750 cfm Edelbrock

Engine should be around 400-425 Hp with 500-525 ft lbs of torque. Looks like I am running lean (very light tan on plugs) and I would rather run a little rich that lean. Any ideas on metering rods, jets and secondary spring to use on this set up?

Thanks in advance,

John
