You're thinking of the intake Manifold. The heads are actually aluminum. And yes, I am referring to the set that you can get at airram.

 

OK I see. When I hear "HO Heads" I think of the 4.7L engine, with different output versions.

Ported/polished heads benefit any engine.

Almost all modern, naturally aspirated engines use glass fiber reinforced nylon intake manifolds. Cheaper to design, cheaper to make, lighter, and don't conduct heat as readily. Pretty much nothing wrong with them unless you boost. Or if they aren't designed quite right and shrink over time...

 

yes..i failed bad on that one =)

 

How much do you guys think that the stock bottom end can take? Everything is forged right? If so, shouldn't a built top end compensate for anything under the stock threshold? And if the manifold is composite, how much pressure can it take? They're pretty tough, and the only thing that I have seen to break one of those was a NOS backfire on a saturn. Just gotta find some custom parts and a small lottery worth of money to pull this off. I'm aiming for slightly less than 500HP, but more torque.

 

I'd talk to Twink since he has a blower on his truck and had to have some stuff fixed, I assume b/c of the blower.

 

NOS backfire on a Saturn. Hilarious.

Connecting rods are forged powdered metal. Crank is cast iron. Pistons are aluminum.

You will never make close to 500 HP with this engine. I promise.

 

Even if you did I'm not sure the tranny could take it long.

 

I just had a bit of a thought process. The crank and connecting rods can probably take a bit of a beating, but my main concern is with the pistons. They are aluminum, which means more prone to melting than an iron or forged set. I did notice however, that the bore on the v6 and v8 are exactly the same. So my main question now is did dodge do the smart thing and be lazy? Instead of redesigning a motor based on another, did they just use as many internals as possible for both motors? If so, then that means that there is a forged cylinder set for our motors as well with two spares! If three people bought the set, a fourth could buy the extras from them for cheap! But that's only if they fit. I'm in dallas, and AIRRAM is only half an hour away from my house. I WILL find out if they fit one way or the other. Gonna give 'em a call monday when I'm off.

 

where is airram at. I live in weatherford which is only an hour west of dallas.

 

His site just says dallas fort worth area for the gear installs, so I'm assuming he's close by.
