can any one tell me the push rod length for my 69 302? i have 2 sets and i dont know which length to use

 

should be around 6.8". better measure

 

There are too many potential variables involved to be able to choose push rods without checking length. It is a simple process if you have both push rod lengths, simply use them for the checking procedure and see which one centers the rocker arm tip best on the valve stem.
