Squish Clearance help


Recommended Posts

Hey everyone! Been lurking the forums for a while, just never made an account. 

 

Anyways, I have a 2006 shee that I'm turning into a 4mm stroker.  I reused my old domes and chucked them up on the lathe and cut them to fit the new pistons. Im sitting at .047 Squish clearance right now, I'm wanting to run 91 octane, around 150 psi. I'm thinking my squish needs to be more like .055-.060 to achieve those psi numbers?  Motor is not broke in yet, but the current cranking compression is 230 psi lol.
