Thread: Change SB OEM Oil Pan To 7 Quart. Car Sits Low

Tweet

I like firebird77clone's suggestion above, as I did the same thing years ago. I would not recommend starting with a chrome pan, however, as those pieces are usually from an offshore source. I'd begin with a stock Chevy pan....one made originally by General Motors. I also like Denny's suggestion of a remote dual filter arrangement. I've used the Trans-Dapt dual filter units on several engine swap projects and they work great. Use premium Wix filters or the best offering from NAPA, which is made by Wix.

While you're in there anyway, this would be a good time to insure that the pickup is the proper distance (3/8" to 1/2") from the bottom of the oil pan. Go to a hobby or craft store and get some of that gray oil-based modeling clay. Some fellows will use Play-Doh, but I have found that it will not hold its shape like oil-based modeling clay. Clean off the bottom of the pickup with solvent so that the clay will stick to it. Make a little cone of clay (shaped like an indian teepee and about an inch high) and smush the big end of your teepee down onto the pickup. Oil the teepee so that the clay will not stick to the bottom of the oil pan. Fit the pan into place and bring it to seated with a few bolts in it. Remove the pan and measure how proud the clay sits up off the pickup.

If the pickup is too close to the bottom of the pan, it is possible for the pump to suck the sheet metal of the bottom of the pan up against the bottom of the pickup and shut off oil supply to the pump. If the pickup is too far away from the bottom of the pan, then you could run the motor out of oil under operation.
