318 marine motors?

The box behind the distributor is the ignition box. The red reset button is the circuit breaker for the charging system, The voltage regulator is also on the same panel behind the distributor. 225 is the horsepower rating. The std rotation engine is just a heavy duty truck long block with all the marine stuff (big cast aluminum oil pan, water cooled exhaust, water pumps, angled intake) bolted to it. Everything in the reverse rotation engine is the same as the std engine but spins backwards, the crank has the grooves for the the rear main seal that are cut backwards and the pistons are in backwards.
Hopefully these engines aren't salt water cooled or they will be boat anchors. Make sure to bring the vaseline when buying parts, everything marine costs about 3x more than the automotive equivelant.
