Q & A
What's in the Box
Bolt-in replacement, louvered windage tray for S/B Chevy champ style pan. Add horsepower and lower oil temperatures.
Works great with pan 91015108 when replacing the steel plate bolted to the bottom of the pan.
Fits in pan 91015137 but there is no way to attach the tray. Will need to come up with a way to mount it in the pan.
Fits with pan 91015106 but it doesn't fit the existing bolt pattern and would require a new way to mount as well as removing the studs in the pan.
Note: Not applicable to # 91015104 champ style pan.
