I haven't done my usual internet searching. I'll just ask the professionals here at SCS. Concerning the modular blocks. Is the 5.4 a bored and stroked 4.6 or is it an entirely different block? I know I've seen some stroked and or bored 4.6's that are 284ci, 292ci, 304ci???

If the 5.4 (329) is it's own block, how big can you bore / stroke a 5.4?

Just curious.

Let's just say you found a 5.4 block from a F-150. What size crank is in this? I'm not doing the math right now, but I'm thinking .030 over and a slightly bigger crank would give you about 345-350ci? Modular 347ci... that got a nice ring to it.

And, what heads would/could you use with this. stock 2V PI heads probably wouldn't flow enough, even with an aggressive cam.
