How much more can i expect from a blueprinted 20 over bore wf than a box stock wf?

Depends on how it's built and what "box stock" engine you compare it to.

Why are you asking?

The .020" overbore won't buy you that much but there are some tricks with the WF that can boost power. It depends a lot on where you race and what the rules are.

i was comparing a 20 over WF built by a very repuatal builder to WKA stock specs to a un touched straight from the factory stock WF.

I'm not sure what a .020" piston by it's self will do but a completely legal WKA / IKF blueprinted WF wll make 1 to 1.5 more HP than a box stock motor.
