Worst Nightmare

If it was me and you do alot of city driving go 4.10 if you do alot of highway go 3.73

[Mr. Land Yacht]

I have 3.55's and I'm happy with them, but I have an AOD, the 4R70W with 3.55's would be even faster, but I'm kinda disappointed that I didn't do the 3.73's.
but, I average about 22mpg on the highway, so, I'm ok with it.
congrats on the 3.73's!

Okay so... My manifold needs to be replaced...

I was looking at other manifolds besides the plastic... the only one I found was an edelbrock victor Jr.

and it wasent street legal...

Should I just go with the stock PI Manifold?

[zwack88]

Damn I didn't see this thread updated. You can replace the manifold with another PI manifold. Just get a manual and it will be exactly how to do it. Now if you were swapping a PI intake on a Non-PI car there are some mods that would need done. So Gadget just for future reference you can throw on a PI intake on non pi heads.

Dorman aftermarket hard parts also has a stock replacement intake available. Any auto parts store should have it.

Its an 03 so its all PI

I just wanted to replace the manifold...

But I wanted to know if theres a better aftermarket manifold that could be put on it.

[p71towny]

there is but they're pricy as hell. as in, unless you have money falling out of your ass, I doubt you want it.

[Sphinx]

True... I don't think anyone has Cash ass... lol

[merc6]

Money hardley ever falls out of your ass unless you are sliding down a pole...
hows the rebuild going?

[Sphinx]

Still waiting for the manifold, and looking for that god damn instruction manual on how to install it..
