Hey guys -

I was told that the 650 could be made into a 750 by boring the block and using the 750 crank, rods, and pistons. I'm not sure if my motor is going to have to be rebuilt or not yet, but I would like to build one eventually (I run an automotive machine shop), and wouldn't mind getting some extra power. :D Anyone know if the heads are the same??

Oh, and I apologize if this has already been covered on the XJ CD, I'm a procrastinator and haven't ordered mine yet. :o

Thanks guys...
