Been having some cooling issues with my 347, so i was hookin up some Autometer gauges today and checking temps w/a infared gun. The middle of my rad. was 50deg. hotter than the bottom(clogged??) i will do a flush. I liked playing w/the gun so i scanned all kinds of stuff, like my headers. They read #1 #5 250-270 #2 #6 280-310 #3 #4 #7 320-360 and # 8 was 480-512 havent pulled a plug yet to look, but what do you guys think ????? I have a few ideas but i would really like some StangNet advice.
