the Lightnings rods are good up to 450rwhp and i just purchased a new f150 5.4l and wanted to know whats the max power i can get out of this engine. a whipple is on the way and id like to get 500rwhp. i also have the supporting mods.

 

Talk to these guys:

 

dont expect 500hp with stock rods...

 

the pistons are good for about 430FWHP without methanol injection. the hyperatic pistons used in these mod motors dont hold up for crap when it comes to excessive heat.
