Hi,
Had a problem with the '41 Dodge truck radiator I had modified and installed to fit in the C8 a while back. The clearances all looked good until the front sheetmetal was aligned and bolted in tight.
Well, turns out there wasn't even enough room between the radiator core and the fan to install the fan belt.

To me, with the economy here so slow, this is a real show-stopper. I simply can't justify buying a new $500 radiator for a toy, plus then having to pay someone to modify it with a long custom made filler neck to fit a cab 11 Chev.
Had to keep the project going, so...
Looked around at my shop and found a couple of nice late '70's Jaguar XJ6 radiators up in the attic. I used to install lots of small block Chev V-8's in these cars back in the '90's using a locally made kit, and saved back a couple of good radiators.....
The radiator fits very well, with a 1 1/2" upper hose and a 1 3/4" lower hose that fits my 235 exactly.
Made some side mounts for it and a custom filler neck and...
disclaimer: no actual CMP parts were harmed in the installation of this radiator.

Thanks, David
