What vehicle? Are you the original owner? Any ideas if the engine was replaced at any time in the vehicle's life?

Can't help you on this but just to show what can happen, at one time I had a 79 Olds Cutlas with a 260 ci diesel. Cylinders went bad and the short block was replaced under warranty. They put in a 350 ci diesel short block, using as many original parts as possible. I don't know how many pieces interchange between the 4.6 and 5.4 but if there are any casting numbers on the block, heads etc they might give a lead on what you have.

Good luck

replacing motor because of head gasket leak? And yes the 5.4 and 4.6 share the same block and other parts. The 5.4 has bigger heads to allow for a longer stroke.

4.6 and 5.4 difference

4.6 and 5.4 share most of the enternal parts. the blocks are not the same, they are the same bore but the 5.4 blocks deck is a little taller cause the 5.4 has more stroke. which puts the intake spacing further apart, which wont allow a 4.6 intake to go on a 5.4. pretty sure cranks and pistons are the same , rods are longer on the 5.4.
