the issue you will have is the pipe fitting the chassis. And why?? the 570 is the only other f/c engine cat made in current time other than the 440 and the 340. If you want to wake that sled up, put twin carbs on it.
Its not that I want to wake it up it that the motor I have now seized up this past weekend. I haven't torn it down yet but im betting its going to be cheaper to replace the motor than buy jugs and pistons. Plus there's a good possibility the crank bearing are blue. An just to clarify the oil was completely full. Not really sure why I didn't get oil.
Someone txt me and last nigh and said id be better off just replacing the stock motor. Is there another 440 fan out there that had more power then the one that came in the jag?
