Another change in progress. One school of thought was that the little motorcycle thermostat does not allow enough flow of coolant thru the radiator. It does seem reasonable that the flow to a small block Chevrolet would be greater, so here we go, changing from a mototcycle thermostat to a Chevrolet one. Out there in the market is a thermostat housing to be placed in the upper radiator hose, which I will modify to replace the original one. Photo two is a photo of one Mark Hubelbank installed on his Zenith. Yeah, I know, my new years resolution was to NOT make any more changes, shot already!
