Hey guys I got to looking around on YouTube earlier and came across a video of a supercharged 5.4l f-150 4x4 with 380 rwhp and i wanna say 420 rwtq and I got to wondering how the stock drivetrain would hold up. (tranny,transfer case,front axle shafts and diff,rear diff)What do u guys think?

You want to know about blown 5.4, look at this;

It'll hold just fine. A good tune and a valve body for the trans will help even more. I drag race with slicks and pull 1.7 60' times. It's a neck snapping launch but she handles it with ease.

Those r some really good numbers. I came from the mustang world so I just wasn't sure of the durability of our drivetrain. Also Blown Ford what's the valve body for I'm not real knowledgeable about auto trannies.
Thanks for the info

Blown yesterday i went to the track to race my truck ran it the first time with ease and the second time i ran it at thr finish line the check engine light started blinking. It wasnt on it just blinked. Then after about a minute it turned off and stopped blinking.. Should i take it to the ford and have them check out all the sensors and stuff or what should i do
