I posted some data yesterday from my father-in-law's old Ford factory spec books. He's a retired Ford engineer and started with Ford in the 50s. I mentioned the 534 gas engine that was used in some Ford heavy tractor-trucks. Some comments were made about the gas engines not having much power. I worked for a moving company that had two 1965 Ford tractor-trucks. One gas and the other diesel. The gas version we had was a lot more powerful then the diesel. I just got looking at the optional engines and I see now there were two diesel options. We had the 534 cubin inch gas engine and the 588 cubic inch diesel. Like I said, that 534 gas was a lot more gutsy then that 588 diesel. There was however, an optionan 743 cubic inch diesel which I've never driven. That one does have more snot.
