I was wondering if anyone has heard anything about stroker kits for the 4.6SOHC motor, and if anyone had access to any numbers for it.

Going big bore would be better.

+1 Plus I hear problems with the strokers like the stroke is too long and comes out from the piston valley or whatever you call it. Big bore would be the way to go to add cubes

Explain Alex ..?? you mean just increase the bore size and leave the stroke alone? just need a bigger diamater piston? how many more cubes can you add? i'm interested...

Correct jsut get a bigger diamater piston, obviously you have to get the cylinder walls bored out but you will gain torque from it. If you search for a guy on SVTP names "nazman" he had a big bore "304" I believe and made good power on a 99 cobra n/a combined with fr500 h/c/i combo.

I would go 5.4 The extra 50 cubes is bound to be nice on the dyno.
