Anyone own a GM 8.1 V8

[jldsc]

The 8.1 is a 496 ci. Basically the same exact everything as the 454, which is as good of a motor as gm's small blocks. I believe its just a 4.75 stroke to get the lil extra cubes and they'll push out lil more horses and torque without having to max out any of the other rotating assly. If you get 14mpg youll be doing good.
