| No; it's not a "Big Al" engine but, it's a 25000 series engine in which the "Big Al" was based on. |

| Lots of the old Allis standby generators out there, if could locate a correct SAE bellhousings and flywheels for truck installation as the stationary ones do not work for that. |

the big 6 was a 844 cubic inch straight 6 cylinder diesel. With a turbo it put out about 325 HP and was called a 21000 series and used in the 21C bulldozer and others. With a turbo and aftercooler, it was rated at 375 HP and was called a 25000 series and used in the 945B wheel loader and others. ------------- Like them all, but love the "B"s. |
