Manifold Questions

[Madhatter1776]

Ok, I am going to be installing a 360 in my 75 duster, I had 2 engines, a 318 out of a 80 something imperial, and the 360 came out of a 85 ram, has anyone ever tried to install the truck manifolds in there cars? if so what do I need to know in advanced, or should I just fit the imperial manifolds? Thanks in advanced

Might want to search bro, it's been done before, no bueno. Too tight.

Most 318 exhaust manifold ports are smaller and will not cover the larger exhaust ports found on the 360 heads.

I used passenger side 92-02 Mag truck manifold on my 69 Cuda. I had already swapped my heads for 302 casting so I could get a good seal. The 360 manifolds have much larger ports. But you'll probably have to get a 340 driver's side like I did because I couldn't get the 360 manifold to fit with power steering. Check out the pics.
You can see the 318 manifold gasket (stained blue) superimposed on the 360 gasket. The 360 gasket almost swallows the 318 gasket so when you try and use the 360 manifold on the 318 you get leaks. Not sure how much difference there is between the engine compartments of the '69 a-body and '75 a-body. I had lots of room left over on passenger's side 360 manifold (had to rotate the 90 degree oil filter). Just sold my last pair of 360 Mag Truck manifolds but they are cheap on ebay ($45-$65)...way cheaper than the 340 driver's side. Here's one for $50 plus shipping.

You can't beat these 2 1/8" plus (exit port dia.) manifolds for the passenger side or even for the driver's side (with manual steering)!!! I don't know more members don't use them???

Good Luck

I was wanting to use the truck's as they are bigger, however the 318 had 4bbl heads on it which is what the manifolds are from, I spent some money on that engine including the heads, but ended up using the block for my truck but not the heads (truck is TBI), I am gonna use the heads on the 360 so I will plan to use those manifolds. Thanks for all the help.
