Builders: Square engine, Over Square, or Under Square for you?

but builders will have their preference, and they'll speak to it :)
I had one of the best engine builders I ever knew, back in my late teens/early twenties, warn me on creating a "shove" into the wall. Now we see massive stroker kits


Oils have gotten way better. So has bore geometry and surface finish.

Pistons today will take more side loading before friction goes too crazy.
