The main dilemna I had was finding a machine shop that was at least somewhat familiar with them.Not that there's anything complicated about them,I just wanted to find a place that I felt comfotable with. Do a lot of checking around if you don't already have a shop in mind. With a lot of shops, they look at you kinda puzzled if it's not a small block Chevy.

Is this the original 216 or 235 or a later block?
