1978 L800
I just joined FTE and would like to know if any of the members have a guess on what my 78 L800 Cab & Chassis would weigh. Vin tag has 27,500Lb for the GVWR. Truck has 204WB, Overall Length just shy of 30' to the end of rear frame rails. Truck has a Clark 5spd.,2-spd rear axle,motor I think is larger than a 429ci. I think it has one of large gas engines that were hand built @ Cleveland Engine Plt.2. Any help would be appreciated.
Thanks,
Dave

N80 = LN800 (gas).
J = 475 4V (7.8L).
V = Kentucky Truck Assembly Plant.
CF3007 = 1978.

15,000 lbs, but you really need to find a scale.
Does it run OK? The 475 is a "smog motor" version of the 477, part of the Super Duty series, originally 401,477 & 534.
They like gas. Lots of it.
If you post the info off the plate on the door, you may be able to get axle and trans info including ratios.
Plans?

Interesting story behind the '475' version of the 477. In the 1970's Ford truck dealer franchises were either medium only, or medium/heavy. Heavy was considered to be 900 series and up, which pretty much limited medium only dealers to gasoline engines up to the 391 XD. Diesel mediums were the Caterpillar V-8 powered F-7000, LN-7000, and C-7000, and the Super Duty gas V-8's were only available in the 900 series, so only medium/heavy truck franchises could sell and service those trucks. The problem was the 391 XD was not competitive with the Chevy/GMC 427 and International MV446 medium duty truck engines, so Ford 'created' the 475 and offered it in the 800 and 880 series trucks. This gave medium only franchises a competitive high power gas medium duty. The 475 was very similar to the 477, as I remember it was cheapened up a bit and didn't have some of the regular Super Duty features. I think the warranty was shorter too. In most sales literature of the time, the 475 was not referred to as a Super Duty engine.

Interesting. I would like to see the Super Duty production figures from 1975 to 1981 what they went out of production. I know very few were built in later years, and most of them went into C series fire truck chassis.
