First off...."Ernkazern" said it in spades!!!! I couldn't agree with him any more. Just tell the boss what you are building and they will do the rest...IF they are a GOOD machine shop. All the high dollar parts in the world won't be worth a sh-- if the machine work in bogus.
That kit looks very good, I always use Speed Pro pistons and rings, just watch your compression ratio. IMPORTANT.... IF its truly a balanced assembly then you should get a balance shop info card showing the bobweight and piston/rod weight etc, ask them for it! If they hem haw around then "it ain't balanced". And if it isn't balanced then have it balanced before you assemble the short block. Very important to have any stroker balanced, If your machine shop doesn't do it they will know who does. I would also use ARP main studs and head bolts, very cheap insurance.
