forged 360 stroker crank-recommendations???

Here, hopefully soon, I will be possibly be using the K1 4.250" crankshaft in my 5.9 magnum. Not to sure on how such a long stroke is going to affect the piston riding in the bore or something else catastrophic. Need to find rods and pistons to go with it but like I said hopefully soon I will have an idea on the price and how it will work.
