That's a prety ambiguous statement; could be taken two ways: Gonna run a heavily milled block, and a milled head (over.100"), for a static compression ratio of a high 11, or low 12:1 in a normally-aspirated engine,
OR
Nine-to-one compression, but a TON of boost from a supercharger or turbo for some outrageous street power on "110" pump gas..
Which is it? I can't figure it out...:?:
