1969 Race Dart w/ 426 Hemi- garaged for 45+ years

So cooooool. I would pull the plugs and squirt some oil in there and put the plugs back.I would be tempted to turn it over at the crankshaft bolt but that's just me.You are doing the right thing tearing it down after 45 years of sitting. I also would keep what green is on the hood (left and right) and Satin Black the center and scoop. Welcome to the site! You will learn so much from all the great people here.
Oh, and keep the pictures coming. We love pictures.
Thank you. I like the satin black idea on the hood
