I am quite upset that certain things may not have been investigated when the engine was out.
In my ignorance, I simply requested that my mechanic "investigate all things that should be investigated while the engine is out."
Nothing was cataloged, nothing was measured, no tolerances checked. Just a timing chain and gaskets.
That was probably 800 miles ago.

Engine, intake manifold, heads, transmission = original. Mechanic had said last time that the engine "is clean" so it is probably bored 30 over. Mild cam but don't know what it is.

Definitely starting with "why it's broken" - but not sure how far to push it from there! I am weary of stroking the original engine... But am open to upgrading the quality or performance of moving parts in the engine. Open to getting the heads machined as well.
