I have heard more bad things about a 216 then good so I am leary about trying one,the oiling system to the rods seems goofy to me and gets me wondering what they were smoking back then. I just cant see that type of system working in a heavy duty truck but I guess it did,I am beginning to think I can find a 261 easier then a early 235 to convert but I would like a original looking motor. I am starting to get confused with all I am hearing so time to drink a couple cold ones and worry about it later.
