Dyno testing

Crazy as it sounds in 1982 i ran no fan on my street driven 70 duster guessing 11 to 1 had 180ish cranking comp general kinetics hft 300r 507 lift 243@50 108 lsa rhoads lfters torker 340 650 dp nitrous it all came about i blew water a pump killed the radiator it was a clutch fan. Fixed the radiator new pump tried no fan it only started to get hot after 10 min of idling if i was stuck in traffic id shut it off the car was possessed i swear. I did run it with no front bumper the chebby folks could not believe it did not over heat it also had 3.23s 727 with L60 14s 26.99 tall it trapped 108 in 2nd gear something else the chebby guys could not believe . I tried to run no fan on 2 other A bodys both 340 cars they over heated quickly no dice crazy right? yes the temp gauge worked right! ran full timing no pinging good gas back then
