348-409 help please...
 

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.

its a 61-64 truck 220HP 348....

Checked out the engine today and the block casting is 3798962... I went to Bobs 409 Page and he has this series liseted both in the 348 and 409 categories, the 348's being different years than the 409. My engine is a 1965, are you sure I have the 220hp 348 still? Thanks for all the help.

i am not 100% postive but thats just what your suffix code came out as....
