It's a good motor for the price. I have the 260 hp version. The only thing different between the two is the cam. If you are buying it brand new then the price difference between the two motors does not justify getting the 290 hp version. You can put a better cam in it yourself for less.
That being said, these are low compression motors. Expect to replace the heads to get anything past 300 hp. In fact the compression sucks so much you'll probably loose bottom end if you cam it too much.
PS. They only get the rated HP with headers, free flowing exhaust and intake manifold. HP rating is at the crank.
