Couple of questions here...

first question:
I recently rebuilt a 292 and transplanted it into my 1954 Chevy 3100 - stayed with a mechanical fan, and staying with a manual 4-sp transmission (so using the bellhousing/crossmember mounting).

The mechanical now fan sits fairly low on the radiator (as in a 18" flex fan hangs below the radiator a couple inches), which I assume is not great for air flow through the radiator. I can drop the radiator down a couple inches and pretty much reduce any overhang. Fan is about 1" or a little less from the face of the radiator.

Should I be using a shroud? most stock/aftermarket shrouds I'm betting wouldn't fit as the fan isn't centered, but there are the "universal half shrouds"

second question
Regarding the stock 1954 chevy temperature gauge, is is just marked as "C" and "H" with a few hash marks between... anyone have an idea on how these hash marks relate to a number for the temperature? The same as the earlier models (47-53)?


Thanks for the help!
