how much hp will i be missing out on by not getting those heads? my setup will be hughes airgap, cam (dont know specs yet), and hemifever tune.

 

Depends on your cam specs

 

30-60 HP depending on cam specs.

I would just ditch the airgap and get the heads.

Here is a good thread that shows you don't need to buy a 600 dollar intake to get 60 ft lbs more torque than a hemi with only 20 less HP.

That cam is a mild cam. Made for bottom end torque. You would not have to worry about lift problems and PVC problems.

Cam, Heads, tuner, headers.

Agreed but I was going the 30-50 range.

 

yea but i really hate to put that kegger with the POS plenum pan back on a nice new motor

 

Agreed, when my second plenum change came around i went with the air gap. I havent noticed any power loss.

 

guess i culd always save more$

 

got a 408 and going back to the kegger. Airgap is great for racing and street car applications but not a truck. A real truck should have torque and nothing gives you more torque like the kegger.

 

Not true, do more research:

A 408 needs more air than the stock keg, heads, and TB can provide. Needs to run true duals out the back too, otherwise you're leaving HP AND torque on the table.

Honestly, I don't know if the Air Gap even flows enough for a 408, might be M1 territory.

 

wow your going to use hughes to prove there intake is better! lol

Longer the runner length the more the intake is built for torque, that a very basic theme for manifold design.

The only time the stock intake will not provide enough air is at VERY high rpm and that not what a truck is for.

The only way to see which is better for torque is to use both side by side and compare. NOT by asking hughes. Mopar action just swaped from the stock kegger to the airgap on there drag dakota and 60ft. times sucked!
I am going to do the swap with changing nothing else and see.
