I've lost enough sleep worrying about whether my engine was going to self destruct
by using the stock harmonic balancer. So I ordered a new SFI spec Probe/Romac
harmonic balancer from
Houston Motorsports. I've talked
to a number of people in the know that recommend rebalancing a balanced motor when
swapping balancers, so that meant rebuilding the engine. While the engine was apart,
I decided a few other parts should be changed. This included some forged Eagle H-beam
rods, some new aluminum heads, a bigger cam, and more compression.
