been there done that, as they say. yes the 250 will work as long as it's the style that unbolts from the head. i got some good advice about actually looking for a 250 since the 292 ones are usually warped on the board here. later ones have 3 bolt exhust older ones have just 2, so it you don't want to have any muffler shop work- look out. some of the 292's on big trucks used the 2 1/2" dump but yours prob isn't that- if it is i'll take it off your hands. grin
