After replacing the timing chain in my 455, I borrowed an install tool to replace the balancer. I was surprised with a little lube and a firm push, it slid right on, I didn't even need the tool. Is this unusual for a Pontiac V8? Also my cordless impact has about 130 lb/ft of torque. Is that enough to torque the bolt with some locktite or does it need the full 160 lbs. If so, whats a good way to keep the motor from turning over, I've read some odd suggestions.
