440 Pushrod measurements

Mopar Performance book P4876826 page 217 says 9/32 plus .000 minus .050 maximum.

Pushrod length is critical for two reasons.

One is if they are too short or too long the oil coming out of the rocker won’t hit the adjuster and run into the cup.

Pushrod length also affects rocker ratio. The shorter the pushrod (more adjuster exposed) the lower the actual ratio of the rocker.
