hey, were building a 383 stroker right now. our oil pump didn;t come with a gasket. do we need to use one or do we just leave it metal to metal?

would silicone be okay?

thanks

 

No gasket needed, just make sure there are no burrs that would interfere. Don't use silicone; if any squeezes out it could end up diddy bopping it's way around your oil passages.

When you're checking your main cap for burrs, throw a stone on your die grinder and use it to radius the entrance for the oil passage. There is typically a mismatch at this point between the pump and the main cap.
