Well it is getting much better. However it is really lean from 3000 to 4500 under hard acceleration. It looks like the pump kicks in at 3000 and takes the A/F down until 3500 rpm's from a spike of 18 when the plates open to 14.5 then it looks like the pump shot is over and it goes back up to 18 then gradually back to 12.5 all the way to 6500rpms. It takes 5 seconds for this to happen from the throttle plate opening to get the A/F down to 12.5. It takes 2 seconds for the Pump shot, 1 second to climb back to 18 then 2 more seconds to come back down.

Here is how it was set up
70 idle jet
120 idle jet holder
170 main
210 air corrector
f16 tubes
.00 exhaust/ float bowl valve
40mm chokes
50 pump shot

380 ci 302 with 8.7 deck, Yates heads with huge CFM numbers.
cam - solid roller dur. I 244, E 247 lift 631, 666 110 LCA 106.5 LSA

It was way lean at the top end so I went to 190 air correctors and thats when it got the results that I described above. The car seems to run good but I need to fix the lean spot between 3000 and 4500. I was thinking about going to 180 mains and putting my 210 air correctors back in. Any other thoughts?
