We pulled the old 216 and 4 speed trans from my 48 PU this past weekend. I have a 235 I am getting ready to put in it's place. Are the intake and exhaust manifolds interchangeable from a 1951 216 & a 1954 235? If so I am going to take them off the 216, clean them up good and paint them then stick them on the 235 down the road.
