Question...what is the normal running temp for a 1972 340

Next time it gets hot,, use your heat gun to measure the temps all across the rad., you're looking for cool areas,, I know it's been rodded, humor me...

I'm also curious about the temp difference between upper and lower hose, while hot and running..

Temp difference between upper and lower hose is about 10* ...about 180-170 same across the tank. motor reads as the gauges read 225-230 +

Messed with the Timing didn't seem to change nothing .......still looking into that .... ...I'm thinking trying the flush with some sort of additive it try and break up any calcium that might be in the block .....next Ill just pull the motor when the weather changes and go through it. .......still going to try the Radiator first !!!! Maybe I'm overlooking something,,,,,,I dunno :banghead:
