I totally understand the desire to keep most equipment on the same oil, makes it easy to grab a jug and top things off without worrying about what is in the engine. I would try one of the flexible silicone heating pads. My 2000 K3500 diesel had a factory block heater, freeze plug style, worked very well. You might research that application and see if the diameter would work for the 292. Mine was one of the last Detroit/GM 6.5 turbo V8's
