Longest Stroke available for thee 4.6L Ford???

Hey guys, whats the largest stroke you can fit inside the 4.6l Block? Does it matter Iron or Aluminum Block ? ? ? I consider the Iron bolock to be the best canidate for a large stroker.

I have seen many 3.75" strokers and one ot two 3.80" strokes. Since we are Bore Limited with the convintional 4.6L Block, stroke is the only alternitive.

I have the same questions for the 5.4L block.

Also, does anyone know the largest bore size you can take the new M6010-BOSS50 block to ? ? It comes with a odd 94mm bore, even though they compare it too the 302. I would love to bore it too 4.00". Ford has no answers nor does the many Ford Performance dealers (?) Iv'e contacted.Only real hard facts....no speculation please.
