1937-54 Chevy 6 Cylinder Upper Water Outlet Thermostat Housing Used

Casting number appears to be 829223. This looks the same as GM 3835423 and has the small neck for the 1-1/4" hose. This housing also has the screw hole for the vacuum/fuel line bracket. I have read that you can use this on V8 swaps where you are still using the 6 cylinder radiator to maintain the small radiator hose size.

See pics for details.

From what I can find, this fits 6-Cylinder 216 & 235 and possibly more. Please do your own research.
