I am enjoying this thread, even though I doubt I will rebuild any more engines,
Thanks.
I love that massive 4 main support system GM gave our 305 crankshafts.

Thank you Jim! It makes my day to recieve some positive feedback. I enjoy making these writeups as well.

Did you rebuild a lot of engines back in the day?

Yes, the GMC has massive mains and rods, a sturdy bottom end for sure. Nothing wrong with a beefed up engine! Adds to the reliability and doesn't need fancy oils to make it last.

Hoping that after all this work it'll go for the 200.000 miles without a major rebuild - as was advertised in the 1960's. I love these engines.
