Could you really take a brand new 402 truck and sit in 90F weather with the windows rolled up in traffic and the AC blasting and it wouldn't overheat?

According to old people I've talked to, no. The one guy I know that had an original big block Longhorn in the day say his would overheat if he did that.

Mine will creep and though it's never overheated, it would peg the gauge if I let it. I wound up adding an aux electrical pusher fan as a bandaid, but I'm really curious if they actually could do it when stock!
