Building a new 505 With Callies / Mopar Performance Block

Took two weeks to get the block ordered it through Roseville Moparts in Michigan.
I thought the block was going to have studs and it came with bolts. Block is at machine shop now I will call them on Monday to see what they think about bolts versus studs. Valley Performance in Michigan is doing the machining work as the block was ordered as a bore size of 4.3150 and now it will be 4.350. They are boring and honing the block with torque plates, installing the cam bearings, checking the deck height (just so I know if it is exactly at 10.72) and finish honing lifter bores. They are also finish cleaning the block for final assembly. Going with a Molnar 4.250 stroke crank, Molnar 7.1 rods (chevy journal size) and Icon flat top pistons. The Trickflow 270 heads will most likely be the limiting factor on the HP of this engine. I was looking at Indy 440-1 completely ported set of heads but it I chose the 270's due to cost and availability also, I just wanted to try them.
