[QUOTE=ltr450ryder;4940468]I've been talking to tony mamo about getting mine ported theres a thread over on tech with a heads cam 6.0L gained 36RWHP with just a fast LSXRT intake ported by tony

 

Flowmasters? Crap.....don't people normally gain 20-40 hp when they remove those? (not kidding).

 

Dam wonder what the 408 would gain with a port job

 

yup from what I've seen theres a vid on youtube guy gained 21RWHP just buy swapping out the flow masters for dynomax ultra flows

 

I have the ultraflo round ones on mine sound good I like them

 

with the lsxrt and good muffler I bet youre looking at 440-450 rwhp from the 390 now

 

Plus it was on a mustang dyno Ive herd they read lower then most dynos

 

Wow! Truck is sooooo sick! Sounds ******* too..

 

thanks dude i see your running 4.56s how you like'em

 

I LOVE them, I just put some 17's today and it is mean, and nowhere modded like your truck. I bet with a set-up like yours it would fly.
