My 409 (or maybe 348) is confusing me more each day. Can anyone help me tell if I have a 348 or 409? The suffix codes on the block end in TF, the block has an X on the front driverside, and the RH exhaust manifold is 3743306. Most of the signs just given would indicate a 348 (I think, not sure about the manifold though) but then I noticed the dipstick is on the passengerside which would indicate it's a 409, right? The engine came from a 1965 C-80. Any help is appreciated.
