Tuning For Detonation

Well, my 160 high flow thermostat was faulty. It wouldn't open. Not even on the stove at 230 degrees. So I had a 195 high flow I stick in it last night. Went to town today. The car ran about 3/4 hot there and back. It normally runs 1/4 to half. So. Got the heat gun out when we got home. right behind the thermostat, under the temp sender it's 179 degrees. The radiator's so efficient, it wasn't letting the thermostat get hot enough to open. lol All the flow it had was the "about" 1/8"bleed hole in the thermostat. If it weren't fer bad luck........went back into town and got an Eddy "high flow" 160 thermostat from Oreally. Got that in now and will drive again tomorrow.

Here's the good news. Until it FINALLY got to about half way on the gauge with the 195 stat, Kitty said no matter how hard I crowded it, there was NO spark knock. We might have it licked. I do have a high quality Stewart Components 160 high flow t stat comin, so I'll replace the Eddy with that. The Eddy "says" it's a high flow, but the hole in it is no bigger than stock. Maybe it opens more? Crapped if I know.

Oh and @kesteb I wanted to tell you I didn't mean what I said personally....not at all. Didn't mean for it to come out like that. ALL I meant was there was NO way I was gonna run manifold heat, come hell or high water. That's all.
