NO! The 351W is a small block the 390FE is a big block, these engine series are different... the C6 transmission bell housing is different. as well the 390 motor mount positions are different. If you really want to do all the work I suggest the 460 385 series engine, keep in mind it will require all the engine management controls the computer, unless you have a complete e350 460 for all the components its really a waste of time!
