For those of you that have rebuilt an LT1, I have a couple of questions.

I'm going with stock compression and stroke, either a stock crank and drop ins or a fully forged rotating assembly. Any suggestions on where to buy? How's the stuff from Texas speed?

Also what's the deal with the thrust bearing on these engines? Are they really welded to the block? (Think I read this somewhere) Is it pretty straightforward to replace? I've seen 180 degree thrust bearings and 360, does this depend on stock vs aftermarket crank?

I'm not looking to add power via a stroker kit, I don't want to sink the money into an upgraded fuel system. I will however be getting rid of the current jannetty cam which has never really ran correctly and looking for a different one. Probably katech from what I've been reading but if you have suggestions I'm open to them. It's a track only car, looking to keep near the 550-560 whp I have now with E85. Reliability is the main goal.

If you have some advice I'm open to it, I've rebuilt engines before, I'm confident in my ability to do that, but I've never opened up the bottom end of an LT1.
