How's the engine coming?

I went back and forth a bunch of times on which way to go... The tech guys at ATI suggested to go with the OE size, being in OK. I know when it gets over 100degreea outside my AC isn't as cold as I would like it to be so I didn't like the thought of it getting any worse. Plus I'm doing it more to protect the engine than to get extra horses from the underdrive(which probably isn't that much). I think I'll have plenty of horses anyway, probably as many as the transmission can handle...

And the engine is getting close.. Its been at the machine shop for over 5 weeks. They're killing me.. I went by there yesterday and everything is balanced and the block is honed, all clearances checked and adjusted. Just waiting for final assembly of the short block. Should be next week for sure. I'm getting anxious and I miss driving my baby!!
