Achieving a 7k RPM redline?

Re: Harleys....

But I would use aluminum pistons and forged rods just for insurance. Then get it balanced.

Stock pistons are alreay cast aluminum, and the stock rods are forged. I agree balancing is a good idea.

now ar eyou talking about being able to make power up to 7k or just making the engine tough enogh to handle it

Oh really. My bad. If you want to go the extra mile destress those rods and have them shot-peened. The rods take the most beating out of all the engine parts because of acceleration/deceleration. Shot-peen the crank too if you have the dough. I think this engine can take 8000-9000 rpm's depending on the build. I'm not joking either. They do it with 90 deg. small-blocks. I have no doubt ours can do it also. Of course they have 4.56 gears or more. That also would require a pro-stock type of manifold. A big hole in the hood.
