I class 650HP as big power really and how many engines with this power can you name? Sure there most likely are 700HP YB's out there but those that are owner's have spent a fortune on them and the car itself to get there.

The point here is that by fitting a 200 block does in no way mean it can be "Upgraded" to 700HP as he puts it.

Never knew about the 80's alloy blocks, apart from being lighter what other advantage do they offer?
