Having done rocker arm geometry for years, this tool made it a hell of a lot faster and accurate for that matter. From beginners to seasoned mechanics, this (hard to believe) tool took all the guesswork out of the process. Must have. I love the thing After putting in the P/R I bought after the measurements were absolutely perfect in length. No issues whatsoever. Hard to believe this simple ass tool made the daunting task a cake walk. Not to mention fast (10 min with motor in truck) I watched a YouTube video to learn how to use it and it worked flawlessly

I did not like the facts the factory did not pack this tool with instruction or even printed it on the package. Had to look for video online to figure out how to use it properly. After that I was able to find out my problem with my cylinder head. And find my correct push rod length without guessing like these old timers.

killer little checker.makes sbc pushrod length a snap.not shure how to use one look up on youtube.it is so simple to use.i needed to check my engine.as I have built many sbc's over the years I didn't like the way my rockerarms looked on the studs.this tool assured me my geometry was on but the design of the rocker arms was just giving me a false impression.

Great tool to quickly check for proper push rod length, and correct rocker arm geometry when rebuilding a SBC, takes the guesswork out of it, highly recommended.

I was building a 350 cab for my sons corvette. Decided to go with roller rockers and decided to purchase this tool as a double check for geometry. Working in a limited window of time for the completion of the project, I purchased different length pushrods in advance so I bettered my chances of having what I needed when the time came. Edelbrock E-Street heads with steel full roller arms was used. Using the gage initially gave me the impression that I didn’t have pushrods long enough for my needs. So I installed the longest rods I had and still the gage said longer! I then used the mid lift method, and found that the arm configuration, made it difficult to determine roller center. So I went with the tried and true, valve stem contact pattern. To my surprise, the roller rocker contact was dead center and nearly the .050 that one can hope to see. And this was achieved with stock length pushrods. Go figure! Would the tool have proven to give satisfactory results had I had the pushrods it was indicating? Who knows. But I can’t imagine the desired contact would have been maintained with the close to .300 longer rods it suggested. I have this tool but will never use it as the determining factor. If it says everything is fine, I’ll be forced to use another method as confirmation so might as well skip this one.

Quick way to get close on pushrod length in a minute or less , check everyone on stock motors, they will vary buy .050 across the board
