I have made up a kit to relocate the Oil filter for Small Block Chryslers. I currently offer the kit with -10AN fittings and am wondering if I should offer it with -8AN fittings.


My main apprehension is the ID of the -8AN fittings is around 0.100" smaller than the -10AN and the original fitting. Is the smaller fitting going to provide a detrimental restiction for a mild engine?

Thoughts? Comments?
