Anyone know what this is?

The information on this page covers most of your Regular Production Option (RPO) codes.

If your truck originally had a 305, but now has a 350, you probably have a GM crate engines. I don't think Chevy every offered a GM 305 crate engine, so any time a replacement was purchased, the owner got a 350.

Its got a 400 in it now.

That tag describes exactly what your truck came out of the factory with .
Red inside and outside, fleetside, deluxe interior, gauges, 5.0 2bbl with a 350 trans, vacuum power brakes, tinted glass, 5300 GVW, power steering, AM radio, tire size, spare tire size, etc ......

The one thing I don't see is the "rear axle ratio and if it has posi" .

I wondered where the gear ratio code is to but found out is probably a 2.73 or something. I never thought the 350 could be the trans.

Why would they have it typed as 350 CID if they were referring to the tranny?

They wouldnt type 350 CID if they were describing the tranny.
