what do i need to find out the pushrod length ill need??
is there a tool or something i need??

 

yeah, your gonna need a solid lifter , the same roller-pocket distance as the ones your using, and a push rod length tool

its a pushrod drilled out and threaded so you can extend it

 

summit sells them.. thats where I got mine

 

I think ours is a comp cams one. Just look in summit, they sell them. Turn it out and measure, then order the size you need.

 

Thanks for the replys so far
Sorry for my noobnessbut i still have some questions, would a dial caliper work for measuring them or would i be better off getting the pushrod length tool.
And is there a good article that shows how to properly measure them??
Thanks

Thanks Primetime that was a good article

 

just open up a stock lifter and flip cup and remove spring and shim with washer and reinstall clip and there you have it a solid lifter for checking length and ptv
