I need help on if the jeep grand Cherokee manifolds will work on a 5.7 into an E-Body. I have heard they work but need confirmation on this. If so what year is best for this swap if it makes a difference.

If your talking about the magnum manifolds they will have very little if any clearance on the drivers side. They come up against the power steering. It was so close on my car I knew it would heat the unit so I tossed the manifolds. If your running Manual steering it may be OK. Mine were 95 manifolds in a 70 E body.

The Hemi is coming in everything, he's talking about NEW Hemi manifolds from the Hemi GCs.

Sorry about being so vague. Yes it is a manual steering box E-Body with a 5.7 Hemi. Wondering what stock manifolds will work. I hear the Jeep grand Cherokee will work but need confirmation.

The Mopar 5.7 crate instructions list the Grand Cherokee manifolds as fitting best in a B or E body. List price is approximately $70/ea.

Will those work from any year grand cherokee? And what kind of price you got on those intake spacers? I seen them on another post and have never gotten back to it to ask you about them.

Mopar lists them as for a 2005 GC. I am not sure if other years take the same part #.

I was hoping thats what you were gonna say because those are the ones that I ordered. Thanks for the help.

I used the Charger/300 manifolds on my abody with manual steering. I would think that they would fit no problem in a e body. The car manifolds appear to flow a little better then the jeep ones.
The top one is a 6.1, next is a 5.7 car, next is a Grand Cherokee, the bottom is a Truck/Durango.

Bringing back an old post in case anyone would like to know, these are Jeep Grand Cherokee SRT-8 manifolds. They are a little different that the SRT8 car manifolds.

So which flows better, the Charger SRT8 manifolds or the Jeep Grand Cherokee SRT8 manifolds?

will any of those above fit a 340?
