Leigh- make sure the machine shop knows they are NOT working on a Chevy engine. Pontiac V8's have the front cylinder biased opposite the Chevy, so if they aren't paying attention, they'll hang the rods backwards!
Looking good!

Though I have read that some people have made the mistake of having the rods facing the wrong way, I find it odd. All the builder needs to do is put the chamfered side of the rod towards the outside edges, where the surface is also chamfered. It is really a hard mistake to make IMHO, unless the builder is a complete newbie. I have seen a more common mistake being that the builder doesn't realize their is an inner oil gallery plug nearest the distributor. I like to have all the gallery plugs tapped and a "squirt" hole drilled in the plug closest to the distributor to help with oiling there.

They figure out something is wrong as soon as they see no oil pressure. LOL
