Blasphemy! Well there is some truth there...302’s perform their best at high rpms fo sure.
I had an 88 Bronco with a 302/AOD combo and it worked pretty well for off-roading and driving around.
Engine was a roller with a mild cam, gt40p heads, and shorty headers. Truck had 6” of lift on 35’s and 4.88 gears. I could get 18mpg on the highway, I road tripped in the thing quite a bit and calculated my mileage pretty regularly.
So...it did have two scenarios where I wished I had more torque down low.
First was in really thick snow or mud...I mean thick like almost up to the bumpers. Water was not too much of a problem.
Second was at high altitude. I drove the truck from Ohio to Oregon one year and the speed density fuel injection really had a hard time with the altitude. When I hit Cheyenne Wyoming and started up into the mountains power dropped off dramatically. I had to downshift into 2 and drive at like 45mph. I don’t really know if this was due to the fuel injection system or the fact that it was like -10 degrees but I thought it was worth mentioning.

I am still considering a 300 six for my 76 F250...maybe I’ll pull my 390 some day when I am finally sick of getting 8 mpg!
