2V to 4V
No, not even close.
MMR makes adaptor plates to use a Coyote intake manifold
on a 5.4 block , with 4V heads.
There is no real solution to this issue , closest to it is a GT500 intake
to a 5.4 block with GT500 heads. But you will need to use the one belt system.
(Water pump, AC, steering pump, and supercharger will need the same belt.
You can run a 4.6 Cobra lower pan to Cobra 4V heads, but the manifold is too
narrow. Adaptor plates might help here, but none are made.
Navigator heads on a 5.4 block will need turbos.
If anyone made a simple 2V to 4V manifold for the 5.4 engine, they would be awsome!
