Here she is, nearly complete on the stand. Cougar was nice enough to help my drop it in the engine bay today, so it should be running early next week.
The previous engine I built last summer died of unknown causes. The #1 cylinder knocked on startup when it was cold (to much pistons-cylinder clerance), and it recently started knocking badly until it warmed up. When I opened it up, I saw the #3 top compression ring was deformed and the bottom compression ring was broken to bits. The cylinder wall was scored, and the pistons were worn badly where the rings fit in.
Anyway, here is the new engine in all it's glory:
bored .030 over
Diamond pistons
balance rotating assembly
the head is milled .090 for more NA compression (Hope to swap on a turbo friendly head before long
)
