I has a speed inc 370 I have diamond -15 CC pistons, Eagle rods with L19 bolts, and the stock crank. Not sure what bearings they used. Diamond makes the best piston for boost in my opinion. The rods are kinda the econo brand in my mind but they are proven peices many many times over. Speed inc took this same motor (with the regular rod bolts) to 995 RWHP and high 8s and drive the car everywhere. If thats not proof of a great motor for the $ I dont know what is.

Is this a used block? We use Diamond and/or Wiseco pistons

Typical for a build like you're explaining we would use Diamond 11517 piston

In that case bore it .030"

Used blocks we normally deck them .010-.020 and use a 6.100" connecting rod with stock crankshaft, diamond pistons are stacked up to be -.010 out the deck ( at stock deck height). With using the shorter rod you end up at 0 deck after machine work.
