hi i need to know what is the pushrod length and rocker arm length for a standard 272 that is out to 292

What do you mean?  Those don't necessarily change.

Rocker arm length is not usually a spec people look for.  Do you mean rocker arm ratio?

yes the ratio and there are 2 different length pushrods  apparently.  i bought new rods and they are slightly longer???

If the significant change is that you bored a 272 to 292, then the ratio and pushrod length remain the same.

Pushrods required depend on the heads, with '54,'55 and '60-'64 being long and '56 to '59 being short.  Factory rockers were 1.43 or 1.54:1.  High ratio are marked ECG.
