I purchased a 1968 chevelle, and got a 350 engine with it. I also received three harmonic balancers with it. Is there a particular one I should install. They are all different sizes.

So John did you find an answer? Do any have a GM number on them? The 350 is an internally balanced engine and came mostly with a 7" balancer, but some did come with an 8" one. Depends on the year of the engine and what it was originally installed in I guess. For the most part though they had a 7" balancer.
