4.6 vs 5.0

On a motor swap is there any differences from from a 5.0 to a 4.6? Will the 50 oz flywheel and harmonic valences from a 5.0 work on a 4.6?

---------- Post added at 07:21 PM ---------- Previous post was at 07:21 PM ----------

Will 5.0 heads and intake work on a 4.6 block also. Thanks

I assume you're talking about a coyote 5.0.
The coyotes are 8 bolt cranks, and 4.6's were both 6 and 8 bolt. I do not believe they would interchange, and same for the heads an intake. The 4.6's were internally balanced. You could swap some 5.4 stuff and 4v 4.6 stuff between the 4.6 blocks however.

It's about the 5.0s that they had before they made the 4.6. So the 5.0s before 1994

Oh the windsor based 5.0. Well in that case, I can tell you its a definite no. Those were OHV (over head valve) motors. And the 4.6's were OHC (over head cam), a completely different design. Nothing is interchangeable.

Well they look different too. Intakes, heads, and timing cover are all different. And Ford didn't start using the 4.6 in mustangs till 1996. Although the 4.6 was around since about 1992 in some forms. I recommend using google and search for images of both engines to identfy what you have.

Gt40 heads will work only on the windsor small block based motor. I would recommend reading up on them as well as the modular based 4.6/5.4 to get alittle mote familiar. I could post all day about the differences, but there's a plethora of information already available out there. Wikipedia is a good place to start.
