5.4 swap is just plain ignorant!
I made 371whp/495rwtq with a 5.4, stock bottom end, cams, heads and intake. Mods are 75mm tb, plenum and dropin k&n filter and a 75 shot of nitrous with a little clutch slip. So much for being ignorant With the 175 jets, clutch slip was rediculous and it still managed 450ish rwhp. With a clutch that will hold the tq, Id say it would be good for 475/625rtq. BTW, this was untuned and on 93 pump
