All in all, a very interesting description, but can anyone tell me
how inserting a plate between the block and the crankcase lowers
compression ratio? If the author meant "between the block and the
cylinder head", this would make sense to me, but since he goes on to
describe the plate's added benefit of stabilizing the crankshaft, I
suspect this isn't the case. Can anybody enlighten me?
