Calibration dwgs

[TexinCali]

I am trying to verify which calibration dwg would apply.

1978 F-350 XLT SC 460 with GVWR 9200
It is originally a California Truck equipped with only, as far as I can tell from the partial engine decals, egr and evap.

I viewed a nice image of 7-97J-RO (Thanks Mil1ion!) which I had thought was correct but noticed a 0/#8500 designation.

So I am thinking this is not the one I have also seen reference to 9-66G-RO but I don't think this is correct either.

Anyway if anyone knows the correct # and/or has a diagram that would be excellent.

Thanks in advance, any help is greatly appreciated!

You have been given the only one compatible 7-97j-R0

The F350 should have a 8500 lb axle
I can try to find the vacuum routing diagram iyw.?

Mil!ion thanks the diagram would be great if not too much trouble.

I see my mistake, if the 8500# on the calibration is Axle wt. then it would apply as mine has the D70 7400# axle.

I thought that referred to GVWR which in my case (Super Cab) is 9200# which puts it in the Heavy Duty Emissions category even in Californina.

I believe there were '78 F350's (standard cab) with as low as 8300# GVWR which would be classified as a Light Duty vehicle in California for that year.

Bottom line is truck is runnning well and passes smog so this is all an academic excercise for me, trying to learn as much as possible.

Thansk again your time is much appreciated.

I believe the 79 had a cat, smog pump and some other stuff not applicable to mine so no need for that one.

That "fact book" link is cool! Thanks!
