Yeah, a little pricey, almost the same price as a set of push rods from Smith's. I will definitely measure before ordering, but going through the charts and all the chatter on line, very little distinction is made between hydraulic and solid liter assemblies. The most common mention is either 11.263 or 11.406 but never associating them with the lifter style and/or year. It is incredible that these engines were so popular in circle track racing at one time, yet the documentation is so scarce.
Thanks
