manifold info

[75ddart]

Looking for stock exhaust manifold casting numbers for a 1975 dart sport 360, what I have been able to find appears only to go up to 1974 models. Trying to find out if the manifolds that are currently on my 360 are original or have been replaced sometime in the past. Not sure the of the factory headpipe size either. I currently have 2 inch headpipes but was told that a 360 should have 2/14, so I don't know. I had the head pipes made up localy about 3 years ago and the guy that did the exhaust said the old ones that were removed were 2 inch so he just replaced with 2 inch. Any info would be helpful , thanks.

Can't speak to the 75 model year, but, that book has BS numbers for 340 exh manifolds.

Got your PM....checked my 74 Duster 360 Manifold Numbers as requested.

As Follows:

Driver Side

3614668-1
7-13-73 F

Passenger Side

3418623-1

Both have the Pentastar to the right of the casting numbers.

next question is are you looking for an upgrade or you need to keep it numbers matching? magnum engine's have better flowing manifolds if thats what your looking for

a 75 dart doesn't have nearly as much value as the earlier ones so stock shouldn't be an issue

Would like to keep it stock as it's a numbers matching car, with build sheet, bill of sale ect. 8Ok miles and supposedly their wasn't many produced with the 360 in 75. Less that the duster 360's so I'm not sure. I know this era car is a smogger but most I've seen are in fact the earlier models with other motors. I realize the 73's with 340's would indeed bring better money, but still I think this car is somewhat worth keeping it somewhat stock, don't know. Thanks for the manifold numbers, will see if they are the same as the 74 models years.

Here's a driver's side one.
It's off my '75 360 Dart Sport. I don't have a passenger's side one, but i suspect it would be quite generic if i know Chrysler!
The one picture has it compared to a 360 truck manifold.
And no, it's not for sale!
I hope this helps you.

Thanks for taking the time with the pics and measurements. Looks exactly like whats on my 75. will check the numbers from your pics to mine, hopefully they are the same.
