i thought i would give you guys an update on my 68 engine rebuild. long story short is that we found that the cylinder that we knew had no compresion has a hole in the piston. the rod is not broken and it kinda looks like burnt piston like you would see on an engine that had a little too much No2. we are obviosly going to have to replace it.

we were thinking that our engine has non-stock pistons because they are domed but we can't really remember what stock ones looked like. a pic or discription of stock ones would be very helpful.

i'll try to get some pics up of the hole in the piston.

any theories of what happened?
