I have a chance to buy one out of wrecked HD21, been stored inside for 5 years. Anything to watch out for?

A supercharged 844 would be out of an early HD-21. I don't know anything about them but my Amish buddy in PA has four of them for parts if you need any.

Buy it !! Could you fit it into Darryl's D-21 puller???

bad part is all the supercharged engines were buda/lanova style. parts are very hard to get. pistons unavailable, sleeves from later engine might work. bearings, NOS needle in a hay stack, they are different from later thousand series engines as they have smaller crank journals. i have a non supercharged version in a parts HD16
