Motors just fine on the highway, all that frontal area kills mileage above 75 mph but not the speed. It will easily run 90+
VolarieDon has seen the 83 D150.
AJ, the stock cam in your lean burn era D truck coupled with its low static compression, and a conservative ignition curve is really restricting that motor. I am not saying that a similar build with a v8 could not do as well.
I am saying it does not take extreme work to get a slant to run well, and when you are done, it’s not just another v8. Either you get that or you don’t.
