I suspect that the 3.4 is the same size case as a 3.2 but with bigger piston bore/stroke so is a relatively easy upgrade

I think the 3.6+ is physically a bigger engine so space and fitment will become more of an issue.

The ECU is also a higher version so wiring and sensors are more of a pain.

Like the other others are saying a 3.4 may be the easiest upgrade, 3.6+ and there will be more things that need to be adapted.

Someone has to be first and should document all those adaptations that are required.

I'm sure Jake has already created a higher displacement engine based on the 3.2 size case, which would be an easier option for fitment.
