Default Intake manifold options..

I have a 408 picked out. I'll have it in 8 months. It will see boost about 8 months after it is in and broken in.

I need an intake.

Apparently the FAST 90/90 cant take 25 psi of boost. I'd like a metal intake, but I don't want to cut my cowl. What happened to the thread about metal intake design options?

I don't want it to break the bank either, but I know it will be pricey.

Have you looked at the aluminum Weiand-liggenfelter manifolds. they say they cost around 800 new, and there is one on ebay for 500.

For a 408 look at the 96mm inlet intake. They are a sponsor here, the intake is aluminum.

um, 25 pounds of boost on a 408? Is this like an all out drag car or something?

^ will be.. 25 psi max. I have 110% confidence in the engine. I'm still in the designing phase, planning out fuel system mods too.
