LME also recommended Circle D so I have contacted them.

When LME sent me the boxes to ship my heads back to them, I immediately saw that the boxes were labeled Hennessy #2, and that LME does all of Hennessy's heads. So that's a good thing here so whatever LME finds they'll be familiar with since it's their parts

Finally got the heads off today and found two issues. The first was a broken harmonic balancer and second a seized lifter so that was the noise that I was hearing that caused me to shut it down. As far as we know, nothing's wrong with the short block

ATI super balancer. It has the OD pulley bolted to the front. The pulley is fine, but the hub of the balancer is damaged.

Yeah on blown or nitrous cars above 800 HP they recommend an annual rebuild (<$100). It’s been a few years so I’ll probably have mine done this winter too.

First I've heard of this. You learn something new every day. Thanks.

Might my new crank require a different balancer offset?

Hmmmm... I am thinking i might have to do this as well! I really wish I would have done this when the motor was out of the car! :/

I shouldn't have sold the oil pan with my short block because LME doesn't have one. Where should I look for an oil pan?

I have an LT4 oil pan - do you need this? Switched to a dry sump system
