This may sound like a stupid question, but what parts will fit on a 4.6 3v from a 4.6 4v. It dosent have to be a terminator cobra. It could be from any n/a cobra (96-01), mach 1, lincoln aviator, or even a mercury marauder.

Well, it is a rather pointless question because nothing but the basic short block between the 3v and 4v engines are mostly interchangeable. The blocks and reciprocating assemblies are only basically the same but even the pistons are different between the 2 types of engines. My suggestion is don't bother giving this anymore thought.

Say if I wanted to rebuild my 4.6 3 valve or a 4.6 4 valve of some sort and I had some 5.4 truck engine parts lying around somewhere, are there any parts I could use from that engine and if not, what similarities do 4.6 and 5.4 engines share?

Is it possible to install cobra heads or and 4 valve engine parts on a 3 valve engine?
