Bracket engine, what would you build and why?

I know I'm showing my age hear but that et at that weight does not sound like a mild 440 to me. Care to share some details?
thanks for the pics, that's a great looking car you have there!:burnout: I am building a 73 Plymouth duster and it is getting the drive train out of the 73 dart. I hope the duster is 3000 pounds or less with me in it. one the engine here it is
73 440 block 0.030 over with wisco flat top pistons
eagle rods/ stock forged crank
gasket matched wieand tunnel-ram to 650 dp carbs converted with pro comp main bodys
mild comp solid roller. 264 at 0.050 and 634 lift after you add crane 1.6 roller rockers
mild bowl ported Indy EZ heads and stock intake ports. porter racing heads specked the cam and worked a little on the heads for me. mostly just fixed Indy cylinder heads crappy valve job/bowl port.ran out of money to have more done to them.
TTI 2x3-1/2 headers
at the time i was using a 9.5 dynamic converter that only stalled around 4200 rpm, with my cam i should of been using a 5200 stall
weld 15x8 drag light wheels/ M/T 275/60/15 ET street drag radials.
8-3/4 with 4.30 gears, was using a set of 4.10 but blew them up on my 5th pass right after i got the car running.put the 4.30 in becasue they was used and in good shape. haven't blew them up yet.lol think the car would be faster with a set of 4.10 in it again.
oh sorry the compression cam out to around 10.9 but i tell everybody it has 11.1. all passes were made on 93 pump gas you get at the gas station.
I have sense then installed a ATI-8 inch converter that i had Lenny at ultament converter concepts redo for me. now on the street the car will stall to 5200-5400.installed 3.5 exhaust to the rear axle with dyno max bullet race mufflers and got a set of the M/T 275/60/15 radial pro tires. the car fills like a whole different animal now, but have not been back to the track in a few years to try the upgrades out. life and health have got in the way.I was going to build a pump gas 512 striker for my dart at the time, that's why i bought the Indy EZ heads for when i was ready to step up but that never happened. the engine is very low maintenance all i do is change the oil when it needs it, change the plugs once a year and check the valve lash once in awhile. well hope this answered some of your questions. oh guess i lied the car weighs 3520 with me in it and after i first got it running my best pass of that days was 10.66 but i blew up the 8-3/4 on the 5th pass that day so didn't get to do any tuning etc. I think i could of got the et down more becasue my first pass of the trailer that day was a 10.92. the last time i had it to the track i let my friend drive it that weighs around 100 pounds less than i do ran 2 or 3 10.49 passes back to back. the car was the same except i went from 4.10 gears to 4.30 and let my friend drive the car.so i will say it weighed 3420 with him in it.I don't know how much HP the engine is making, but i would like to build a 512 stroke motor so i can run some 10.00 flat in the 1/4 in street trim. well sorry this is so long just board and got to typing.lol thanks Bobby
