You will need to have your machinist measure your new forged pistons compared to your cast pistons and make sure your cylinders have enough clearance before they are installed in the block. Also, a torque plate is important whether your building a blown engine or not.
Clearance to the bore? What is acceptable? My current set has .0015 according to the build sheet.
As far as the torqueplate though, I just want someone to confirm that it is OK that it wasn't used for my particular street engine purposes. If I was building a racing engine then I would definitley have it done now that I know about it. They didn't do that from the factory did they?
