5.4L Rebuild Project Question
I'm planning an engine build for my 2002 F150. It has a 5.4L in it, I'm going to be rebuilding another 5.4L to replace this one (with much less km's) I've got BIG plans for this puppy... Anyways, my question is, how much HP can my stock crank withstand? Should I look into upgrading it? I'm shooting for the mid to high 300's off the fly.
