Finished the front of the imp motor today. I’m glad I used the “tool” to install the balancer hub. It’s pretty much a guarantee you’ll strip the threads out of the crank if you try to run it down with the bolt like a gen1 sbc. My butthole was a little puckered bringing it in even with all the threads engaged in the crank.

Tool? I use allthread. Weird thing is the hub seems to seat way far out so the last long block I put together I stripped a few chunks until I realized it was already seated and I was wasting my time. The LT motors really aren't the devils the internet makes them out to be. Since I got mine right in 2015 it's been bulletproof and I stand on it 20-30 minutes at a time with it running hot as fvck. Last year I vented the driver's valve cover and picked back up around 15-20whp. I vented it after I overheated the absolute fvck out of it. Buried the Autometer temp gauge, a first. It was pissed, but it came around. If it didn't, I had a spare longblock just waiting.
