Im picking up some valve covers from Craigslist today for my sbc. The seller also has a sbc oil pan he is getting rid of. Its pretty old and appears to be an oem oil pan. My oil pan on my 78 chevy k20 has a big patch on the side of the pan. I tried googling but i can find any information on if all sbc oil pans are the same depth or if they are different for a car vs a truck application. I dont know how deep my current pan is to compare it to the pan for sale. Does anyone know if a generic car pan is shorter than a truck pan or if they are the same depth?
