hi all, I have a 340 with crane 1.6 rockers and I'm trying to figure out the pushrod length?. I believe stock ones are 7.5 inches? But I need ball and cup pushrods, any help would be greatly appreciated. Thanks

So you don't have any push rods at all?, Go to a push rod web site and it will explain how to measure for correct length, and terminology used for ordering. Get it wrong and your out the cost.

i do have some smith rods they measure 7.75 but can't torque down shafts.

You need a checking pushrod first, once you get it you can use it to see how long exactly your pushrods will need to be to order them. Second thing is which lifters are you using, solid flat tappets, hydraulic flat tappets, solid rollers or hydraulic roller lifters? They can all have different cup depths and some have different body lengths, especially in the roller lifters I sell both Mantons and Smith Bros, PM me if you need help on getting what you need

i gave hughes engines a call, they over nited me the tool, then shipped the correct PR to me .. all done very quickly
