Beginner's Bucks-Down /6 Build...Suggestions Welcome

Hello all. This is a great site. I have spent hours browsing here and at /6.org and have gathered a treasure trove of information. That's the hard part... so many good ideas, it's hard to choose exactly what to do.

I am working on getting the car now. I hope for a 68 Dart 270 more door, but I will be OK with a 70-74 Dart Custom more door. Running or not, as long as it's a solid foundation for a good build and is not wrecked. Running preferred, though. I'd like to drive it during the week and wrench on it on the weekends.

As I said in the title, it's a bucks-down build. I'm planning to do this over a 3-5 year timeframe and I want to use as many used / junkyard / rebuilt parts as I can. There is much I can do myself, and much I'm willing to learn from others concerning this build.

I'd like the car to be street-only, run a bit faster, handle, and stop a bit better than it did when new. With that in mind, based on what I have learned, I have come up with the following tentative build...

Engine= '72-'74 head if '68-'71, '73+ electronic ignition with orange box and Pertronix coil if '68-'72, NGK ZFR5N-3459 plugs, '71+ stock cam if '68-'70, Offy intake with 2v adapter plate, Holley 2300 350cfm 2bbl., stock manifold > 2.25 headpipe and Y-pipe > 2.25in / 2.5out muffler > 2.5 tailpipe.

Transmission= B&M Shift Improver kit

Rearend= '73-'76 8.25 if '68-'72, SureGrip and 3.23:1.

Suspension= OEM HD / Rallye with front sway bar.

Brakes= '73-'76 LBP front disc / rear drum if '68-'72.

Steering= '87-'94? Dodge Dakota 2WD manual or power rack and pinion.

Wheels and Tires= 14x6 steelies with dog-dish caps, Goodyear 205/70R14 or 215/70R14.

Other Mods (for later)= Holley 390cfm 4v #8007, Dutra Duals?, 2"? dual-exhaust, Head= 318 valves, 340 springs, street port and gasket match, milled .050 for 9.0:1CR or .090 for 9.5:1CR, Oregon Cams #125? 212/206, 415/399, later lockup converter A904 TorqueFlite?.

What can I expect, over stock, with this build? Suggestions for changes welcome. I know there are things I have overlooked or not considered. Thanks for your time and consideration.
