It had the 350. Dad had the pump played with so it was pushing a little more than that. It had the T2090 9 speed with 38K rears on camel backs geared at 4.42. I believe it was 220" wheel base. It had the level IV interior and it was blue. That superdog gave every 425 CAT a run for its money. The truck looked a little rough on the outside because for many years it pulled a rock bucket, but, I can assure you mechanically it was sound. Dad bought the truck in the mid 90's from a Mack dealer in south Florida. It was a twin with another one they had on the lot. They were consecutive VIN numbers also. It came from the factory as a day cab, which from what I understand is quite rare. It had a dash full of guages (trans temp, rear end temps, air filter, etc...). As far as the chasis number goes, I dont know what it was, but, I'm sure I can find it with some digging. The only pictures I have saved digitally right now are after he wrecked it. There was not much body damage to the truck, but, as I mentioned earlier parts were becoming a little hard to come by so the insurance company scraped it. I told him he needed to buy it back and he is kicking himself for not.
