How much horsepower

now you got me scared! would also like to know what that came out of, or if it is just someone trying to sell parts. Well, if my 360, which is built very similar to Il dusters breaks the eagle SIR rod I am sunk. Already got way too much in this motor, expensive rods would have broke the bank. If that rod broke with the engine at 7500 or so, it is almost understandable. Anything can be broken.
