What is the max bore for stock pistons?
Hi!
I got the 318 engine. I took the heads off and measured the bore on every cylinder. The range is between 3.9164 and 3.9167, so the bore is + 0.006. Do i need to bore over or just hone the cylinders.
Thank you!
P.S. I apologize for my language - still learning it...

The book I have by my computor is the Mopar Perf B/RB enginebook. It specs .0003-.0013 clearance. I would think you are w/in spec, but you should check a manual for your year and size engine.

But + 0.006 is more than .0003-.0013 clearance, so this is not good? Maybe i do not understand?
