How many cubes can you get from a 4.6 and 5.4?

I believe a 4.6 can be bored and stroked to 5.1 litres. The 5.4L engine can be bored and stroked to 5.9 or even 6.0 litres. Liveronis Motorsport has a 5.9 Litre in the works. The 2v or 4v does not make a difference in terms of boring or stroking a engine. However a stroker 5.4 with 32 valves would make incredible power.

The mod motors are being developed and re-developed everyday so my answers may already be outdated.

I tried searching, and couldn't find the answers. Some people I work with want to know, and I haven't a clue.

So how big can you get with a 4.6 and a 5.4? SOHC vs DOHC isn't going to make a difference, correct? Forgive me, i'm not modular educated!

SHM offers a 5.2 (318ci) DOHC Cobra long block & I know that Mod max offers a 5.7L (350ci) stroker kit for the 5.4L & a 5.0 storker kit for the 4.6L. However I don't know is these are the absolute biggest Strokers offered.

Edit: I see that SHM now has custom blocks you can order for the 5.4L which can boost displacement up to 6.0L. Not really a stroker kit but the displacement option is there.
