front cylinder stamp LW340LR1H ??????



L = ?? (on passenger car LAs this would be 1975)
W = Windsor, Ont engine assembly plant
340 = engine cu.in.
LR = Left Rotation ?? (R would be Regular Fuel on a passenger car) * maybe Left rotation & Regular fuel
1H = ?? (on passenger car LAs this would be an assembly date)

anyone have another LA Marine engine for comparison
& I thought the "MARINE DIV." engine assembly plant was in Marysville?

Were they selling a 340 Marine engine in 1975, if so what compression?
