I think you could get it in 270HP also.

Yes also on 270HP(RPO469C), but according to the Spec guide, only available after Jan 20, 1958.

If it has RPO 684 it could help confirm a 290HP FI if the vin is before the January availability date, approximately vin 3200 or before.

There were several ECLs associated with 684. Unfortunately there is no data supporting which ECL relates to which build. But since 684 required either a 3-Speed or 4-Speed transmission, it would leave the Powerglide automatics out of the equation.
