72 Demon slanty-to-340 Resto

OK so this project will start moving forward pretty soon. I just picked up some part time work, so money will start flooding in eventually. I got loaned an engine stand and cherrypicker, so sometime in the coming weeks I can pull the slant and 904 (whenever one of my friends has a free day to help). My project checklist right now is a bit in disarray, but I figure my first steps are partial disassembly and rust repair, then I can get to a point where I'm ready to mock up (I have my 318 ready for mockup currently). Eventually I can do parts like subframe connectors and suspension parts, I know powertrain is a major focus but something tells me chassis and suspension are a good starting point. In the meantime I'm lookin out for a V8 K-frame, what's a good price to get one for? The only ones I'm seeing are for a slant and a V8 frame up in WA for $350, but at that price I could just toss in a couple hundred more and get a QA1 frame and cut weight off the front end.

P.S. @72bluNblu I found those 1.03" torsion bars you mentioned 1.03" Torsion Bar - A Body
