do a big bore stroker

boostedsvtsnake

to answer the guys question a 5.4 has a taller deck height than the 4.6. other than that, its basically the same motor. 3.552bore for the 4.6 and 5.4 unless you get the block re-sleeved. the 5.4 also has a much longer stroke of 4.165. there are not as many(HA, ZERO) intake options for a 5.4 if you don't want the blower, unless of corse you go with sheetmetel. the big bore 5.4 goes to 3.700 and can result in 366ci if you have the right block where as a big bore 4.6 can get you 324ci with just resleeving the block. hope this helps
