I know I have to buy a pushrod length checker to see what length pushrod I need but what diameter do I need. There are also different length checkers. I don't know which one of those to get either. What do I need?
stock are 5/16 diameter. You could use a set of 3/8 with 5/16 ends to fit into the stock lifter cup end, but it is not a direct bolt in and IMO you are fine with a set of 5/16 hardened ones that are at least .100 wall diameter.
For a length checker, you can get them from Summit or Comp Cams. If you have a pedestal style setup, you probably will need shims a well. There are hundreds of tech articles on how to check for the proper length.
Thanks! I just realized that I could have found the answer myself. I forgot that I'm a member of www.sbfbuilders.com. Just finished watching the video. BTW, it's an awesome site to be a member of! Woody really knows his stuff.
