I am replacing my 250 engine with a 292 this weekend and I am having concerns about what to do with the dip stick. The 292 tube is very short and I don't have a dip stick. My 250 tube is long and bolts to the center of the side cover plates. Is the side cover center bolt hole in the same location on both the 250 and the 292? and if so are these interchangeable? The 250 is from a 1978 and the 292 is from a 1965. Thanks Perry
