I hope you guys aren't talking inches...

4thou is on the tight side.. I'd running a wiseco piston I'd run 4.5 to 5 thou for up to about 600.. over 600 and you'll want more. If you can keep the motor cold you can go tighter just know that you'll scuff the piston if you can't keep it cool.

Remember the wise man once said... if you build it loose only you know... if you build it tight everyone will find out!

Piston to wall clearance 0.42 - reliable

I don't think .42 ptw would be real reliable.

I consider longevity reliable. I'm not planning on ever exceeding 600whp. I want a moderate tolerance that doesn't suck down a quart of oil every 1000 miles or has piston slap when cold. 0.42 seemed like the right compromise. What are your thoughts?

I was making a joke. As .42 is damn near 1/2".

I'm sure you meant .0042??

Just ball bustin'
