Back from the machine shop

So I got all my parts back from Aims... well most parts.  I brought them everything I had with plans of having them build up the short block.  After talking numerous times with them about options and feeling uneasy after every conversation, I decided to have them do the least amount of work possible.

So they hot tanked the block and cleaned basically everything but the heads (still not sure why they disassembled the heads and didn't hot tank them).  I told them what it was for and that I was looking for them to build up short block.  I asked about options and they ultimate gave me pricing for some really expensive pistons and a rebuilt crank and set of rods.

I did some research and found a complete Scat rotating assembly for 100 bucks more and they were concerned the 3.98" stroke would mean the block would have to be clearanced.  Meanwhile any bit of searching will tell you people are putting 4.25" stroke cranks in these things.

I told them I would end up purchasing the rotating assembly and they decided that they would bore it for me even though I had not received the pistons yet.  I asked if they wanted to wait until I had the rotating assembly and they said it wasn't necessary.

I went to pick it up and they had thrown out my old pistons and pins, and I had to ask to get the old crank back.

I measured one side of the engine and everything seems to have been bored accurately.  They installed freeze plugs and oil galley plugs and didn't charge me (hopefully they did a good job cleaning the oil galleys).  They also installed the cam bearings which seem to be good.

As for the heads that they disassembled I took them to another machine shop and they found that they were both cracked.  Surprised Aims didn't mention that especially when they disassembled them.  On to painting the block and tracking down some new heads...
