here is a little proof of no corvette motor in the impala..the top end is completely different..all factory impala come with multiport...not tuned port...big difference..http://www.geocities.com/gbeard12020/Impala/9625e.JPG
i was looking at the spec sheet...260hp and a neck snappin 330ft lb of tq.....with a few mods....it would be nasty..the cr from the factory is 10:1...
