Not wanting to plug Mercruiser but they announced that they were doing an 8.2 "of their own." I expect it has a lot to do with previous 501 cube 454-based offerings. It was promoted to the dealers starting this Spring but it was not real this summer when I bought what was probably the last of the Crusader 8.1s. But if you need the displacement/torque it is worth checking to see if it is available.
Also, when cruising around GMs web, I see that they are anouncing a new smaller displacement V8 with some impressive torque and HP ratings. It will be interesting to see if (probably when?) Crusader will have a version of this. Between its output and less weight, it may be a good option for us big block folks.
Good luck,
