The original question was, Stroking - is it a good idea? Here's the short answer. If you're drag racing the car, then yes, it's a great idea. If you're driving the car daily to work or for pleasure or to a show, then I would recommend not stroking it. The piston speed isn't the thing that bothers me so much. It's the fact that the piston isn't staying square in it's bore half way down. Too much side loading was enough to turn me off. That's my 2 cents. Good luck.
