It is not a 4v DOHC motor, and it has "tall" gearing, so it will not rip up the rev range. Which for tracking, isn't necessarily a bad thing.

My uncle works at a GM engine factory and works directly with John Rydzewski (one of the main LT1 engineers). So I can tell you for certain that the dry sump Corvette and Camaro LT1's are indeed nearly the same. The only real differences are as I said, pretty minor like accessories (intake could fit this category), exhaust and a few other things (like the Camaro has a built in sort of oil separator thing), all external stuff for the most part. The main guts of the engines are the exact same, nothing substantial was changed.
