Thermostat range, marine V8

Posted by John Wallis On 2012/8/17 16:55:39

Finally getting the marine V8 finished and am wondering what temp thermostat to use (there are two, one on each bank). As I recall, the 1956 374 used a 180 deg from the factory. The cooling source is raw water routed thru the oil cooler incorporated in the modified Hash oil pan, then thru the exhaust manifolds (I assume to both cool the manifolds and to "pre-heat" the cold water entering the block) then the normal path thru the block, heads and then out to exhaust.

Cooling should be no problem, as most raw water sources will likely be in the 50 to 80 degree range.

Thanks,

John
