the 5.0L block making mad horsepower will flex and the first thing to crack will be the valley

Valley girdles are cheap ways to increase the strength of any ford block very well worth it and surprisingly not very well known to street bangers. Horsepowersales.com has a set for $250 and with those installed on a stock block they ran 1000 hp on that thing and have yet to split a block! Like i said very well worth the cheap price, and easy to install as well.

Valley girdles go under you intake manifold on the block above the lifters and help keep the block together under stress with high horsepower.

It just seems to me that a valley girdle does the same thing the manifold does, hold the two sides of the block together. how would two little pieces of metal with a couple 1/4-20 bolts help you hold an additional 500hp. sounds a little fetched to me

the website for the valley girdle talked about here says they filled the blocks with block filler on those 1100hp motors, I don't think the valley girdles were doing shit.
and the blocks split from the bottom up, throw a good main girdle on and that's about the best you can do.
a well balanced, lighter rotating assembly would help a lot too.
