360 timing

p225/70r14 98s rear tires.*direct fan with shroud has cowl gasket but front gasket was removed and is in trunk. Will measure rad. Size this weekend. No scoop. The aftermarket temp gauge isnt working at all. I just bought a replacement for it. The dash gauge barely comes up but i believe it is working. My non contact thermometer reads about 145 at thermostat/top rad hose area. My guess is that the thermostat has been removed. I have a 195degree one that i hope to install this weekend. Sunpro Tach says 2000 @ 50 mph but at times it can be jumpy. I plan to replace it.
