GT350 vs '18 GT manifold for the F150

[SFLEcoboost]

Hi Guys,

I've been mulling over swapping the manifold on my '18 F150. I'm not looking to wind out the motor, just want more herspers. I know both net more power on the top end. I don't tow or haul anything, so I'm not worried about that and I don't plan on locking out the IMRCs.

Its a 2WD truck with the 3.31 rear gear. What is the cost/benefit of both manifolds?

Thanks!

Wouldn't it be better off doing gears and tune vs manifold on a truck?

I would like to stay with the 3.31 gear.

So what are you trying to gain then? The manifold currently on the truck should be most optimal. Without really doing other things i dont see the benifits.
