I have a 350 with a 1969 intake manifold on it. I am going to replace the gasket so I was wondering if it would be better to keep that manifold or get a different stock manifold (money issue). The truck is an 82 but all the emissions was removed by the PO and they don't test around here anyways. I got my 82 carb to fit on the 69 manifold I just want to know which one will give the best performance or if there is a difference. Could a leaking intake cause some burning oil or is that not possible? Sorry for all the questions. Thanks a lot.
