Have them measure the compression distance when they pull the head.

They are going to check everything including rechecking the ballancing that was done.

Good. But you need to get the compression distance now before the engine is disassembled so you can estimate what you have in compression ratio, and will be able to start making good informed decisions now regarding what you might want/need to do. If you are looking to make this a high performance engine, you need this piece of information before you spend money on anything else.

I finally heard back from the machine shop. All the machine work that was done is good. The bore, balance, hone, all that. They recommend decking the block and surfacing the heads and redoing the valve job. The pistons are good quality but the rings are low bid. The machinist said they used mismatched main and rod bearings as if they just used left over parts from other jobs.
Basically this engine was a good start and could have been run as is.
I got it for $800 so I think I got a good deal. Just have to tweek it a bit now.

I've heard of engine builders using bearing halves from different sets to tweak the final clearances. I'm not saying it's right or what I'd do, just putting it out there.

Congrat's on a good deal otherwise.

Yeah, not sure about that either. The guys at the machine shop didn't mention that as a possibility but could be. Just showed me the ones they took out and there were 3 different brands and one that wasn't marked and was a different color than the rest. Kind of weird.

Should get it back next week and get my tranny from Passon Performance in a couple weeks and be close to driving my Challenger. Just in time for winter...

Right, but not from different manufacturers.

Did you get the compression distance or compression height of the pistons from the machine shop?, or piston manufacturer and part number?

I didn't. I am just doing a street engine, not going to go really wild with it. Just cleaning up a few things that the machine shop recommended and put it together and run it.
