motor work

Im going to have my block punched out to .30 over, having it decked, and balancing the bottom end. i got a quote of $750, thats everything mentioned above plus all new cam berrings, freeze plugs, and boiling. Was wondering if thats a good price or should i keep looking? i was told to go to this place by a guy i work with who allows them to do all of his race motors. id like any opinions and suggestions about this or any other works i should have them do while there, and what type of pistons should i go with??
 
The shop I use for all my machining charges right around $500 to mag, deck, clean, square, bore and hone, new freeze plugs and cam bearings, and balance the rotating assembly.
SInce your getting new pistons you will have to pay more to have the rods and pistons pressed off and on, and I am sure he'll resize them. Might want to upgrade to ARP rod bolts, they are the weakest item in the stock bottom end.
You'll need the pistons before he bores the motor and before balancing, along with the new rings and bearings.

If these are a stock crank, stock rod, small valve piston I would look into the Probe FPS series pistons. Or you may want to look into one of the Summit Rebuild kits, the price is hard to beat for what you get...
