what size push rods?

[rculjak]

Hey guys, I am about to start my afr 165's, trickflow street heat, stud mount 1.7 rockers and 70mm TB install and a have a question. With the stud mound rockers, what size push rods will I need, I am leaving the bottom end stock and also leaving the stock cam in place, can I reuse the stock push rods?

No, you need hardened pushrods because of the guide plates.

You'll have to measure for yourself, get a little 15 dollar pushrod length checker. No one can tell you what length pushrod you need for motor.

how do you use the pushrod length checker, Ihave no experience with valvetrain geometry.
