I will keep an eye out for it! It doesn't have the cooler on the side of it if that matters...

My bad... it does have the cooler on it! Its complete. PM me your number and I can text you some pics if you would like... It came off of my LT4 that spun a bearing. I cleaned it really good but I am sure LME will clean the crap out of it!

Continuing the story...
I learn something new every day. As we pulled my engine we found pieces of a diamond coated washer that was supposed to be between the balancer and the crank timing gear, but it had been installed behind the crank timing gear. The washer is there to bite into the surface of the timing gear and the balancer so that all the load isn't on the keyway. Probably caused the hub failure in my opinion. Hennessey originally installed the bottom assembly in June '20, but it's been removed and reinstalled since then. I took the windage tray off the pan to remove the big pieces, and found metal in oil and in the pan. The washer was in 3 pieces and when the crank hub broke it put some metal into the oil as well. Also a lifter was stuck and made some grooves in the lifter bore. It had LS7 lifters but LME is installing Johnson lifters. We now have to clean the oil cooler out or replace it. This entire saga began as I pulled into my garage following some very ... spirited driving, and heard new and strange metal-on-metal noises. I had no idea about any of this at the time. All of this might only be helpful if you find yourself taking one apart.

Was the balancer dual keyed?

Yes, but it was an ATI super balancer with a pulley, not a solid balancer, which is what I'm putting on it this time, which is the ATI CTS-V & ZL1 LT4 balancer, with the hardened HD hub and dual keyed.

I thought some might like to see LME's short block and heads specs. I think they're sending their startup dyno sheet next week.

Great stuff! Out of curiosity, what oil viscosity are they specifying that you run?

It will be broken in on the dyno using either Driven 10W40 Breakin oil or the Valvoline VR1 10W40. When I receive the engine they recommend I put another 500 miles on the engine with a quality non-synthetic oil, then after I put the additional 500 miles on the engine, switch to synthetic oil.

Is the camshaft that is shown spec specifically for your application by LME or is it from a shop?

Yes, specd and supplied by LME. It turns out they did the motor that I bought from Hennessy. This new engine has a lot more cam in it than that one did
