yes,70s came with a shroud,I would install one,It will help the cooling system.180 to 210 would be fine to operate your rat, what ever you do, do not overheat that fresh motor, 67rat member #199
I'd try to keep the temp around 180 to 210 as 67Rat said. My Elky constantly runs cool at about 180 to 190. As for the fan shroud, you can purchase it from a number of companies such as YearOne, OPG, or our sponsor Ground-Up.
