Why would I need custom pushrods ? Just asking ,I would think that I would be able to use the 85-89 LA roller pushrods, from a Diplomat 6.764" length ?? Not sure about that. Also not sure if I would need solid pushrods, or the hallow pushrods ?
When a cam is reground material is taken off of the base circle (everything except the tip of the lobe) which then sets the lifter deeper in the bore so in most cases longer pushrods are required. LA motors can use either solid or hollow pushrods, the rockers are oiled through the shafts.
