Frequently Asked Questions

What stroke will our pans clear?

All of our pans will clear a 4 1/8” stroke, depending on which rods are being used.

What front oil pan seal does your pan use with the timing cover?

All our steel pans use the thick front seal. Our aluminum pans use silicone seals.

What should the clearance be between the pan and the oil pickup?

You can calculate the clearance by measuring the internal pan depth and measuring the distance from the block's pan rails to pickup bottom. The difference between the two measurements will provide the pickup to pan clearance. Gaskets will add some additional clearance. We recommend clearances for all pans to be 5/16"-3/8”.

Why use a louvered windage tray?

Windage trays are louvered to reduce windage horsepower loss and to provide quicker drainback for oil thrown from crankshaft at high rpm. The louvered design allows oil thrown from rotating assembly to drain into sump without splashing back.

What is the drain plug size?

Our drain plugs use a 1/2-20.

What is the bigger hole on top of our kickout oil pans?

The bigger hole is for an oil temperature sending unit. It is a 1/2" NPT.

What gasket do you recommend?

All of our oil pans use the thick front seal gasket.
