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

well darn, I think your doing what you want and that's great... but the FIL surely took care of that engine, so some nice oiling in the cylinders and a fire up would have been cool. I bet the engine would have ran perfect
Thanks. It may have started and run but for how long...............I didn't want to risk permanent damage. This is a long thread and lots of documentation. You will see it did have some issues and one of the heads was bad among other things documented in the many pages here.
