I need help figuring what push rod size you guys are running for 49-410-8 cam shaft. I'm using the stock rocker arms.

Not too much different. It adds a bit lower end torque and suppose to help gas millage. I'm not 100% certain on its specs. But I know the base circle is smaller.

The stock cam was
.384/.402

Performance cam
.465/.5

By the way it's it
Intake needs to add .081 to the pushrods
Exhaust needs to add .098 to the pushrods.

Now this is a not true the only way to fine out for sure buy a push rod checker. They make two.
One is a plastic pice that sit on the rock.
Second is an adjustable push rod to get the length.

If the lifers have been primed no need to add if the are dry I user add .020 for lifter.
