What heads and intake are you going to use? While he didn't use that block it's the same idea that Jon Kaase used for his 410 ci. 4V that he won the Engine Masters Challenge with a couple years ago. He used a Ford GT block re-sleeved to a 3.7" bore and a Sonny Bryant crank.
Why do you want to stroke it? Just cause you want the cubes or do you think you need it for the HP you want? Unfortunately nobody makes an OTS stroker crank for the 5.4. PhilllyC was working on a 349 and 363 setup and has a thread about them. Stroker cranks for the 5.4 mod motor
. His 349 crank and rods with that block would get you a 366 ci.
I think Tweeked used that block with the stock stroke in his NA build.
