Do you have a 500 + hp LS that your beating on right now, that gives you first hand experience on how it can outlast a older stroker? plenty of these new engines develop piston slap, you should be able to tell us why they do since you looked into how they clearance the newer engines, tell us for instance how the piston is sized to the bore..
There are thousands of strokers mainly the old 350/383 chevys that have over 100K

My dad does. Was putting out 700HP. Right before he broke it. But to be fair the thing got beat on very hard. 7000RPM+ was the norm. It was the titanium valve train that failed. That was our fault. Should of keep an eye on that stuff. Every thing else looked good when we opened it up. Stronger valve train is in the works along with a whipple charge for 1000+HP:snakeman:



I asked my dad why he has such big bores and only a 4 inch crank. He said it is not good to get a motor out of square. Stroke bigger than the bores. He said keep the stroke short so it will rev higher and quicker.
