318 race engine 4104230-318 any info. on these engines?

to 1qwikscamp i see the pad that you are talking about right above the oil pan but there is nothing on it???? And i don't see an X, R or R3 or the mopar logo on it. also the timing cover is off it right now but i could only feel 2 bolts on the crank not 4. Any help????
