Looks as if there cannot be that much difference between the two engines then.... a hundred pounds at a guess? I guess it must all be cumulative @ 10-20lbs per multiple items. Cast heads, cast blocks, cast manifolds on both? As to the LA designation, I thought LA was lowered A and RB was raised B, since deck heights were changed on both?
