The note for this adapter says differently. The note for this adapter says that you are to use a 1986 or newer oil pan, so why would you use a 4 piece oil pan gasket when the newer pans take a one piece gasket?

Oil pan gasket part number 91010224 is the ONLY gasket that I offer which is correct for this particular adapter. It is actually a very simple deal. This adapter uses the exact same oil pan and gasket that the 1986 and newer engine block would use stock. Please disregard all other recommended items you are seeing on this listing for the moment so you don't get yourself confused. I assure you 91010224 is the correct gasket for this adapter number 91015011. Sorry for the confusion on the suggested parts shown at the bottom of this listing. I am working on getting those corrected ASAP.

91010222 gasket Why would you use a 91010222 4 piece gasket if according to the notes you are suppose to use an 86 and up oil pan? There is a lot of confusion happening here and it has already cost me a lot of time. You keep calling these parts "Remain conversions" and this has been going on for months and I keep hearing that "someone" will check into it and it has never happened. They are called "crankshaft adapters".

This conversion is made to use a 1986 and newer oil pan and oil pan gasket. Gasket part number 91010224 is the correct one for use with this conversion adapter. Conversion part number 91015010 uses a 1980 to 1986 oil pan and oil pan gasket. You could certainly call these a "rear main conversion" or a "crankshaft adapter." Those two descriptions are one in the same when it comes to a small block Chevrolet engine. Sorry for all the issues you have had. If you would like to give me a call I am extension 2947 and am here on the tech line from 8 to 5 Monday through Friday. I would be more than happy to get you on the right track with this adapter.

An oil pan and gasket for an '80 to '85 SBC are required with this adapter. Our gasket part number 91010222 or Fel-Pro 3441818 works with this adapter.
