Radiator or engine off center?

[DusterDaddy415]

Looking for some advice here. I have a ‘72 Duster with a 360la swapped into it. I have been updating my cooling system.
I installed a new cold case radiator and went to put a fan universal shroud on only to find out that the radiator is off center from the engine. Is this normal for a swap like this?
My car has the small 4” bolt pattern for the wheels. Could my issue be because it was a stock 6 cylinder car? Any insight would be appreciated.

Mopars mount their engines offset to the passenger side about 1 1/4" in the '67-'76 A bodies.

A picture would be helpful here. As long as the fan and shroud match up, it's likely correct.

See post 5 of the 70-up Cold Case rad in my car with a factory 70-up shroud. You can see its off center by design.

Cold Case Radiator Shroud?

Is anyone running a shroud on thier cold case radiator? If so what are you using? I have a Cold Case MOP755A 22 inch radiator in my 69 cuda. I have a 360 with the 70 up aluminum water pump, so I have the passenger side lower return hose. The way the Cold Case shroud mounting flange is made...

Factory shroud is offset 1 1/4 "

They have to line up the rear pinion with the output shaft so what's cheaper: 2 different motor mount brackets and a plastic shroud or 2 different axle sizes and 2 different axle tube's?

Radiator is basically centered.
Engine, trans and diff are all shifted to the pass side by by design.

The universal shroud is the issue. Also if it is the typical box with a big hole in it, it will cause you more issues then if you don't have one.

All A Bodies were 5x4" bolt pattern till some time in the early 70s regardless of engine.

Through 72 all were SBP. From 73 up the disc cars were 4.5" and drums at all corners were still 4". Nothing bad about small bolt pattern unless you have high HP and slicks.

good to know. just getting back into mopar. I had a ‘74 Dart Swinger years ago but it had a nice set of mopar ralleys on it so I never had a reason to check the bolt pattern.

Yeah I thought about trying to cut the universal shroud up but I figured the same thing, too much hassle. I’ll get an electric fan at some point.

if you look at post after post about my car over heats / runs too hot..

you will find a commonality...

Al radiator and electric fans and or boxy shrouds that sit almost right up against the core

There are Electric fans that can and will do the job Ford Contour is one and I suspect any from V* dodge challenger and charger but I don't know about the fit.

BUT...

You have to do things to account for the added electrical load, and the thermostat switch etc. mechanical fans will work fine, and be reliable 99.9% of the time

No reason for electric when the factory parts work best. The rule of thumb is: your radiator is dirtier on the inside than what you think. Overheating in traffic or lots of stoplights is usually a missing fan shroud. Overheating on the highway is usually a slant six rad on an engine with a hot cam & compression, or dirty rad, or similar situation.
