I am just curious as to if there is any difference between a Y7 and a Y8 block. In other words, is there any difference whatsoever between a full Y8 engine vs a Y7 block with a Y8 head on it? Will a hybrid have exactly the same output/reliability/compression ratio etc compared to dropping a complete Y8 in? I am fairly certain this is the case, but I would like some verification before I take the dive. Thanks in advance, Cheers.
