for checking pushrod length? I have read Jim Miller's article about proper valve train geometry and since I am using stamped rockers in my 283 it would not be possible to use his method for setting the rocker height. I am hoping this tool along with the adjustable pushrod will help me set up the valves, rockers and pushrods with the correct and most efficient geometry.
Using just an adjustable pushrod (bought or home made
) and some machinist dye, a sharpie, or even some grease will tell you everything you need to know.
Using stamped rockers makes this a little harder to do because sometimes the witness mark isn't as clear on the valve tip, but if you work w/it for a bit you'll get a feel for it.
Start w/the stock length and add/remove length as needed (rarely will you need shorter p-rods).
