ive never heard of a stroker kit for the boss motor.
I think the aussie boss is a stroker of the american 4.6L modular?

Best do all the bolt ons and tune. if thats not eenough then you ggotta see a boost application

No in fact a 4.6 has 90.2 mm (3.552 in)bore and 90 mm (3.543 in)stroke in a 8.937" deck block.
The 5.4 has the same 90.2mm (3.552 in) bore and a 105.8mm (4.165) stroke in a much taller 10.079" deck block.
So I wouldn't stroke a 5.4 any more than it already is....a custom big bore block is the way to up the displacement if you really want to.
