Thanks for all the info you guys! I have learned, thus far, more about the 6 than I ever intended too in my life!
This engine has a pushrod that seems to have cracks in its cup.. not sure why or what would cause this. The engine sat for many years.. about 20. Then I changed the oil, rebuilt the carb and fired it up after cranking a while in hope to get oil pressure up.
I then ran the motor, for about 2 mins. It ran like poo for the entire time and smoked out the neighbourhood through its 1" destroyed exhaust.
When I took engine apart, there's so much grime that I'm not sure the oil passages were allowing oil to pass or the water passages to allow water to pass.
Seems like a pretty high mile engine, even the oil pump gasket was puking oil on it and it had no front crank seal to speak of.. and no bolt at all in the damper pulley.
~~ The reason I asked ~~
I have rebuilt several aluminium blocks. The rings are often piston specific. If they're not in round with the piston or manufactured for the specific piston, from what I've been told they're not correct and can cause massive issues being not exact fit for the piston.
This being cast block and chromo cylinder walls, I am happy to hear the robustness of them tolerates any manufacture ring and I hope the cast SB engines are that way also.
I just spent 220$ on 4 ring sets for a Honda engine, to make sure they're correct for the OEM pistons. :(
I also have my eyes on a 64 dart 4 door and a Plymouth Scamp that's been in a barn for a lot of years. I have a feeling I haven't seen the end of /6 for many years to come!
