I run a pretty basic setup with a few mods. I have a 72 Duster with an all iron 440, 10:1, old 516 home ported castings, 2.14, 1.81 valves, small roller cam with Harland Sharp rockers, Team G intake with a Dominator, Junk fenderwell headers, 727 with a 4000 stall, a 35 spline 9" with 4.56 gears, cal tracks, and 10x28 slicks. The car has run a best of 10.84 @ 123 in the 1/4.
The car weighs 3400 with driver and all the windows and instruments still work. I am building a 528 for it and hope to run mid 9's.

I'll post some pics soon.

I put my 493 in this past summer I built. Its a 440 block with a 440Source 4.15 stroker kit. 10.6 comp with Indy EZ heads. Indy dual plane and same 850 DP. 2" TTI headers and 3" pipes out to rear bumper. Cam is a solid flat tappet by Dwayne Porter with 264 & 270 @ .050 and .592 lift but I have 1.6 rockers for about .630 lift. I use the same Dynamic 9.5 converter and same 4.30's with a 30 x 9 tire. Its a street car driver as I still drive it to the track and race thru the pipes on pump gas. Best et is 10.76 at 124.49 at 3700 lbs. Ron

Just about to start my 440 build here in Oz, the weight of your car is just about the same as mine and you are running the times I want to run. Any more info on your combo?
