292's have massive amounts of torque and they respond well to go fast modifications, but they do tend to be gas hogs. They share the same bellhousing bolt pattern with the V8's so you'll need to do some mount modifications- - - -a crossmember change and a 55-up V8 bellhousing is one approach to the swap. Of course, it's also going to require an open driveline, so the entire running gear will end up getting changed out. Have fun!
