72 Demon slanty-to-340 Resto

So I talked about this on a couple prior threads, but 2 weeks ago I went over to Boise and brought home a 72 Demon as my project car. For $1500, it's got:

• Slant 6
• 3spd auto
• 7.25" rear end (has the oddly shaped diff cover with the 9 bolt pattern)
  
• New sway bars (included, but not installed)
  
• Hotchkis tie rods
• KYB shocks all round
• Aftermarket strut bars
  
• Tubular control arms (brand unknown)
• Aftermarket brake cylinder and booster
• Drilled/slotted rotors in front

Most of these upgrades set me on the right path, but there are plenty of other things I'll need to change out. For starters:

• Swap the slant for a 340 and find a V8 K-member (may keep the slant for a future project, idk yet). Have plans for alum. heads+intake and a full blown sequential efi setup (edelbrock has a full kit, it's a bit spendy but not too far outta reason considering it's one of few non-TBI efi systems on the market).
• Swap the 904 for a 5-6spd manual, right now the main candidates are Passon's 855 and the Tremec T56 (anyone in the Pac Northwest wanna buy a 904?). The 855 is direct OEM fit, no tunnel mods, but the Tremec is readily available. Thap also means swapping the steering column for a non-auto one.
• Swap the 7.25" rear for a 8.75" and a sure grip (figure 3.55 is a nice round gear ratio to put it close to daily drive-able). Could I make a few bucks selling the 7.25", or is it basically junkyard-bound?
• Stock radiator is toast, half the fins in the first row are gone completely, so a new alum. radiator is in order. Also gonna drop the belt-driven fan for a comp-controlled twin-electric. Between electric fans, new stereo system and the efi system, there's gonna be quite a bit of power draw so it'll need a better alternator. I'd imagine this also means a lot more electrical work than I realize..........
• Came with a front bench seat, but I'll instead go for two buckets and a woodgrain center console around the shifter.
• Depending on how much vacuum I'll generate with the engine setup, I may dump the brake booster and go all discs.

In the meantime, the big task for me is body work. While it's not a total rust bucket, it's an Ohio car so you can guess there's some holes in it.



And now it's an Oregon car
