Instead of spending $1400 for a kit or $950 for just pistons I grabbed an old block and decided to take the low road on this build.

I’m going to use an old crank and block with minimal machining.
Maybe a balance only.
E85 pump fuel.

Which ones are strongest?

I like the design of the kb but it has a high ring placement and no skirt coating.
The speed pros have coating on the skirt and lower ring placement but not sure about material and also gives lower compression.
I know nothing about the Wiseco.
