it always come down to time vs cost vs quality pick any two when doing a project. I have found that free or low cost lumber usually carries a pretty high cost in time.
The bearing bar is most likely babbit not lead. old engines didn't have replaceable bearing shells on the crank and rods they were poured and scraped to fit. Makes for a cool paper weight and conversation piece.

I used a coleman propane cylinder for a remote reservoir on a HF 20 ton air/hydraulic jack. It sure is nice and stable bolted to the top. Upside down is the right way for this application.

x2 on the vintage, working on a 78 my self. Does it have duel tanks? if so and it's a 4X4 the front tank is made of unobtamimum. Don't ask as I don't have an extra one. Did buy one from Rock auto that said it would fit and it doesn't. So be warned.
Good luck with the project they are fun for sure.
depends on the die openings as to how thick and how sharp the bend needs to be. typically the opening should be 8x the material thickness as a minimum. Finger dies are usually used for braking up pans. As far as precision goes they can be quite accurate if you take your time.
