70 Duster 340, 3 Core Rad?

[SSSN8KE]

Did the factory rad for a 70 Duster 340 with A/C come with a 3 core rad?

Thanks

I was wondering the same thing?

The 70 A body factory 340 a/c radiator is p/n 2998945 which is a 3 row core.

I believe the only way to correctly ID which radiator the factory installed is to reference the Build Sheet. The 2 numbers under "RAD" indicates the radiator part #
(line 3 on my 70 dart 340 build sheet)

Then look up in factory parts manual and/or one of Govier books
ex build sheet 45 = 2998945 = 70 340 both trans with N51 max cooling package
This is a 3 core radiator
78 = 2998978 = 70 340 both trans
This is a 2 core radiator
These are the only 340 radiators offered on 1970 A bodies
Above info from Govier books and there is no listing for a 70 340 with a/c
I have both radiators and info is correct

Anyone with more info can add to this

I had a couple of 72 318 w/ AC parts cars, all had the same 22" rad the 340's got, two core. I've never seen a 3 core A body radiator. The 70-72 all seem to have the same series radiators at 22".

My original 2 core 340 radiator needed to be recored so I had the shop add a third core in order to help engine cooling in SoCal stop-wait-go traffic.

The 1970 Dodge Challenger/Dart Service Manual on page 7-10 lists radiator 2998945-22" for the 340 engine with air conditioning. Service Manuals – MyMopar

The OP asked if there were any 3 row core radiators for 70 duster 340
Yes # 2998945

@dd70340 yes, it is called out in the FSM
I was referring to the Govier books where there isn't a notation for 340 a/c radiator

I had some old coot make mine into a 3 core at the radiator shop years ago....

Did the factory rad for a 70 Duster 340 with A/C come with a 3 core rad?

Thanks

Yes. I have one. It’s a factory 318 a/c car (now crate 402 ) which is the same as 340 max cooling pkg. #2998945

dd70340, pa340dart, Demonic, 4mulas Thank you for your replies, much appreciated! I found a 2998945 rad for my Duster. It will be recored. Just wanted to make sure they came with a 3 core.

I found this info which lists the rad for a 70 340 with A/C

Edit. Mine is a 2998944. 318 with A/C

I had my 2 core recored to 3 core. Rad guy said it's a straight forward rebuild.
