If your building a custom valvetrain setup you might consider purchasing the Comp Cams adjustable pushrod measuring tools. They're the perfect tools for making sure you get exactly the right pushrod length for your application.
A large number of variables are involved in determining the correct length pushrod for your application. Pushrod length is affected by any of the following:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm brand/design
- Cam base circle size
- Lifter design/brand/pushrod seat height
- Valve stem length
Don't assume anything when determining the right pushrod for your new engine. A pushrod that fits one engine may not necessarily work in another. Any number of items can be different on your engine, requiring you to use a different pushrod length.
