I have not found much for a off the shelf piston. What the most anyone has sprayed on KB piston?
If a stroker crank isn't out of the question, that can help you in more than one way.
Lots of piston choices plus you can make decent power with a farm tractor reliable package. 9:1 will get you 500 HP/600 FT/LBS naturally aspirated by 5000 RPM. It makes a highway friendly 3.23 gear work with a mild converter and regular gas.
