Externally balanced engine troubles
Hi all,
Started my rebuilt 454 (Originally out of a '78 chevy pickup) for the first time today and found that it has a fairly violent shake that increases with engine speed. The only thing I can think of is that the PO put an internally balanced fex plate and harmonic balancer when they should be externally balanced pieces.So my questions are... 1. How can I tell for sure whether or not my flexplate/balancer are externally balanced? 2. Can I just buy an exterally balanced harmonic balancer/flex plate and install them? Or will I need to get the whole rotating assembly balanced as well? Thanks in advance for amy help -Jordan
