I don't know if they would put that ratio behind a 250, but I have an '85 K10 shortwide with 2.73 axle ratios. The engine is a tired 305. It's really too tall a ratio for the 305. Cruises nice on the highway, but it's terrible slow getting off the line. I plan to put a 292 in next summer. That 4 1/8" stroke should love those gears.
If your axle ratio is indeed 3.08, I think the overdrive would be too tall for use with a 250.
