This is close to my combo also. I'm running a .030 over 440, compuflow ez-1's at basically the same flow you have. The difference is I have 13:1 and a 727. Also weigh about 3400 w/ me. I run the old .690 comp roller. I believe it's 282 @ .050. I've put 3 passes on it so far. No tuning and it went a best 10.24 @ 132. Rear is dana 4.89 w/ 33 x 14.5 slicks. Shifting at 6500.
