Need a tolerance range
 
I'm intersted in knowing if a set of pistons which mic'd at 89.916mm and cylinders at 89.99 are acceptable for a stock 2.7. ANy info would be appreciated.

standard piston size is 89.965-89.975 nikasil
89.952-89.967 alusil

piston cylinder clearance should be .0010-.0018 with wear limit of .0031

good luck hope this helps...
