408 Scat Stroker Kits

Is this referring to a cast crank as well as the forged? Wouldn't 6500 RPM with a 4 inch stroke be a pretty high piston speed for cast?

Not to hijack, but this thread has pretty much changed my mind on using the forged crank. If the cast crank from scat is a little lighter and is close to $500 cheaper, and I don't plan on ever going over 6500 rpm or 500 HP, I guess I should go with the cast? I'm probably gonna be around 425-450 HP on a 408 from the components I'm looking at I think..

And to grow that combo significantly to need a forged crank (100-150 more HP), you’ll have new cam, new valve springs, new heads or lots of $$$ to race port what you have, possibly improved rockers, and most likely new pistons.

At that point do you just build another motor and save/sell/transfer the old stroker motor?
