My 6.1 retrofit thread
One of the considerations with this conversion is the swap from a belt driven fan and the factory radiator to the more modern electric fan cooling system.
1st issue is the radiator.
The G3 hemi runs the inlet and outlet on our drivers side, so the A body rad. is not really viable without a cross over pipe.
The problem is made worse by the inlet/outlet being a much larger diameter than the A body hoses - the G3 runs a 1.75" top hose and a 1.5" bottom hose.
I ended up deciding to run the following radiator - itll require some bracket and outlet modification but will work well when fitted.
Its marketed as a "6.1 b body radiator" - p# cc1643
.......AND B4 anyone says anything....I ran a Champion A body radiator with no issues for 18 mths.....so I have no problem with their quality or fit :p
· Core Dimensions: 16 1/4" high x 25 3/4" wide
· Overall Dimensions: 22 5/8" high x 29" wide
· Upper inlet: 1 1/2"
· Lower outlet: 1 3/4"
(This is an issue as the diameters are reversed to the 6.1)
· Bracket mount system (Hor - 27 1/2")
· OEM style brass petcock drain.
· Billet style fill neck construction (Not Stamped)
· Radiator cap included
· Trans Cooler included
