I've got to replace my crankshaft and have access to a "de-stroked" crank. Any thoughts on this? Supposed to move the power band/torque curve a little higher in the RPM range.

It's certainly possible...I don't think you'll be happy with it unless you make numerous modifications to accompany it. If you run less cubic inches, you need to make up for it with RPM; good rods, a good balance job, steel caps or a girdle to hold the crank in at those increased RPMs... and trans mods to allow shifting higher. Without these things, you'll just needlessly give up torque and HP down low.

In addition to what Kendall says, I think these engines, on the street, work best when there is some load applied to generate heat which spins the turbo. A short stroked engine will have to rev more to generate this heat which will make it not as streetable. Having said that, I may have my thinking on backward!
