Roger: Welcome! Should not be a problem locating pushrods for a 292. Try your local Chevy dealer. I think they are still offered as a GM service part as there are thousands of 292's still in use.
You can also try your local NAPA dealer.
Why not save yourself some bucks and go to your local U-pull-it yard and get a complete set.
Do you have some bent or broken? Usually it is not necessary to use new pushrods to replace a damaged few. Unless you are starting with new lifters and rockers or are going high performance in which case everything will be new anyway.
If you have a used running 292, used rods will work just fine. Make sure that they are reasonably straight, are not split or frayed on the ends. Small minute cracks will start at the edge of the oil hole, and can be easily seen with a magnifying glass. An easy check for straight is to roll them across a table. Again, unless you are going for high RPM, reasonable straight is fine. No 2 pushrods will be the same length in any engine that has 10,000 miles on it. Small variations in valve fit, guide clearance, spring pressure, rocker motion and lubrication to each rocker arm will cause different wear rates and tensions on each pushrod's length. This is why some rods will bend and fail, and others will not on the same engine at the same RPM.
If Chevy or NAPA can't help there are other sources. Manley, Proform, Elgin, Moroso all make or have made pushrods for Chevy sixes.
If you still have to have new and strike out with the other sources, don't worry, I am sure someone here will jump in soon with some more scoop!
Happy hunting and Think Chevy!
