Heirloom - 73 C10 Cheyenne

[Bchain]

I had completely rebuilt the motor in the thunderbird almost a decade before this. I knew, at least, the basics. Me and a buddy even hand assembled, plastigauge, etc the whole bit. It ran great when we were done.

That being said I really didn't want to screw this thing up. I started taking it apart and looking into some local shops for a little bit of help. I wasn't going to farm out the whole job but at the very least I needed a machine shop I could trust.

Inside I could tell it had been put together previously with forged pistons that were 30 over (by the stamp # on the pistons). Further research put the limit on the block at 60 over but I really didn't want to go there. Cylinders looked ok at least to the unpracticed eye. I couldn't identify any hatching and didn't have a micrometer, but there wasn't any identifiable lip at the top.
