Hey guys just wondering if I should install upgraded pushrods when I add the 1.6 roller tip rockers to the 2.8L. If so anyone know the stock pushrod length?
. I bought new pushrods when I installed 1.6 roller-tip rockers, but even doing that probably wasn't necessary, as the original pushrods were not bent. I don't see any real need for "upgraded" pushrods for this modification.

With the talk of stock pushrod deflection I wasnt sure if that would happen with just a rocker arm swap. I know it happens with big cams and heavy springs. I know the aftermarket pushrods like comp cams are made stronger.
60V6 engines have shorter pushrods than most engines, which means we have less deflection. We use a thicker wall pushrod (.083" vs .049") for custom length pushrods but that is only because we needed longer pushrods. You would need a more aggressive cam than stock to see any potential gains from just pushrods.

Unless you have a new cam, I wouldn't really see the benefit. On engines that have zero-lash though, it makes sense to buy new valve train components because any wear actually reduces the effect of the rocker arm. But with the V6, you have to set lash, and can take out any slack on pushrods, even if they're a little bit worn.
I replaced mine, but, I also changed the cam, springs, and rockers. Would it hurt to leave them, probably not. Its one of those "while i am there i may as well" things.

If you have more than .001" wear on your pushrods, they are toast. These are hydraulic lifter engines which have preload, not lash. You would need a solid lifter to be dealing with lash adjustments.
