x2 on not being very street friendly at those power levels. Don't forget you will need to upgrade the drive train as well.

In addition to the previous piston comments, a good machinist would bore that .067 over and need to know what type rings you will be running to properly hone it the final .003.

At this point you are probably considering what crank, rods, and bearings to use.
