Hello all-
I was reading a post on realoldspower.com and, in light of my own goof ups
and confusion, decided to post.
What does a harmonic balancer do? I'm guessing it's there to help dampen
vibration from minute differences in weight in the reciprocating assembly.
Am I wrong?
For my 350 project, I erroniously believed that a 350 balancer was the same
as a 307 balancer and got a 307 balancer. The 307 balancer is all steel. My
'70 350 balancer has a thin strip of rubber between a loop of metal and the
base.
On the 307, how does a solid steel balancer dampen anything? Will I kill
my 350 by using a 307 balancer?
I also have a '55 324 whose balancer's rubber ring is shot. They made two
different balancers that year and mine, according to Fusick's, is
un-rebuildable. One person on this list who used to race Gen-1 V-8's (who I
aproached for advice) has informed me that he ran engines without the
balancer ring without troubles.
A '70 W-31 350, supposedly a nearly perfectly built, blueprinted, and
balanced engine, has a *larger* balancer than a stock 350. Eh? I
understand that they were built to spin higher, but what does the size of
the balancer have to do with anything?
What am I missing?
