I will not argue the HP but a stroker just makes more TQ no way around it.

I need to clarify my statement about the kb190 piston, it is a flat top with a raised area(the kb356 is a dished piston that still has a big dome on one side)and will hit the magnum on two sides of the head, not just one like the 356. If you mill all that off of it you get what is known as a KB107 + a lot less money in your pocket. They work fine in a 360 LA but not a magnum.

I built a 360 LA with the kb107 one time and it vibrated, just a little, then after re-doing it exactly the same with a balance job it pulled a lot harder up top. It did not feel like it was killing itself or anything but it was way happier at 6000 RPM after balancing.
