Gonna be parting out a C3500 soon, need advise

[JeepsAndGuns]

Got the truck and got it over to my friends house. I live in a trailer park, so something like I dont have the room for, plus its not allowed.
I got to check it over a little more. I stuck a battery in it and tried to crank it over. Starter is sticking a bit, but after a few tries with the key, it turned over. Fuel pump is not working, not that it would do any good since the fuel is sour, probably the reason the pump is not working. I had my friend crank it over while I sprayed it with some carb cleaner and it actually fired right up on it. Seemed to run ok. So the engine might be ok. The right valve cover says 454 by tonawanda. Does this mean anything? Since it seems to run and be ok, what would the value be on a used 454?
Pulled the glove box and it has a 1228747 ecm with the bcc ARPY. I tried to find the gear ratio of the rear axle but couldnt find a tag. Do GM axles even use a tag like dana axles do?
I have one month to to sell what I can then I have to haul it off, those were the terms with my friend. I should be able to get my stuff without much trouble. Might go out there in the morning and start on it.

yeah, lots of bigblocks say that, it's just a gm production plant.

unfortunately not much these days, a stock BBC belongs in a motorhome, or it's only value is in a core for a gigantic racecar project or something like that.

Ok, wasnt sure. Not knowing much about GM engines, I had never seen that before.

No tag. You have two options, first one is hope the RPO code sticker in the glove box is still legible, looking for something like GU6 = 3:42, GT4 = 3:73, GT5 = 4:10, etc, G80 denotes a locker. Second on the passenger axle tube facing the front of the truck is a three digit code stamped into the axle tube generally followed by a space and a longer set of number or letters. Post either one here and I can decode them for you.

i have a third option. jiffy marker the input and output, spin, count, grab a calculator.

With an open differentail just make sure that both tires spin one full revolution.

I'll look for that next time I am out there. I have no plans to use the axle, just wanting to know the ratio incase someone calls and asks.
I went out there today and got the hydroboost and master cylinder. I ran out of time before I was able to get anything else.
If anyone here needs any reasonably easy to ship parts, let me know.
