5.4 block strength

[1996mustangGT]

how strong is the production 5.4 block?
how much HP can it handle?

It depends on what production 5.4 block you're referring to. There are a couple of different blocks - The GT block, which will probably handle close to 2,000 hp, the Lightning block, which I think will handle a pretty good amount of power with some good internals, maybe 800 -1,000 or more (I'm not real sure, correct me if I'm wrong) and I'm not totally sure that the Navigator/F-150 blocks are much different than the Lightning ones, but again, I'm not 100% sure. I do know that there have been 1,200-1,400 hp cars that had navigator blocks though, so who knows.

The Navigator blocks came with forged internals likes the 03-04 cobra's did as did the lighting motor as for the F-150 its not a built bottom end but they will handle up to 700HP i believe
