Internal or external balance
Anyone out there know if the 287 Pontiac engine is internally balanced?

I'm almost sure it's internally balanced, but it's been 48 years since I was inside a '55 engine.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
