The combo in my signature is pretty close to what you describe.

So far has run a best of 11.33 with a 4900 flash 8 inch converter and ran a best of 11.49 with a 4200 flash 9.5 converter. I think I can get in the 11.20s as it sits with some chassis tuning. 60s are pretty bad as my best is only a 1.6 even.

Ported 452's(no clue on flow numbers), comp solid [Email]259@.050[/Email], 10.6 comp, 950 Holley, 2 inch hookers, 4.30 gears. All passes have been corked with 3 inch to Edelbrock RPM mufflers, then to 2 1/2 tailpipes. No X or H pipe either. Car weighs 3800 lbs, give or take a few.

By the way it runs fine on pump 91 and the 8 inch converter is almost identical on the street to the 9.5. In fact the 8 inch is WAY tighter on the street than a 10 inch I had in the car 15 years or so ago.
