How to Measure Pistons, That Math Class You Hated in School Finally Comes in Handy!
Ever here the terms .030, .040, and .060 over engines? Those are general terms used when an engine has been machined prior to the rebuild process to utilize a certain size piston. But is it really .030, .040, or .060? In some cases, yes. In some cases, no. Confused yet, probably. In order to actually calculate the final bore size, you have to factor in a few measurements. First off, any reputable machine shop will tell you prior to any machine work, he or she will need to measure your pistons and will also need to know what the application will it be used for, i.e. street or drag racing. So, what are the measurements needed? Well, you will need to know what the diameter of the piston is and how much piston to wall clearance is desired. With those two measurements, you will be able to calculate the final bore size and from there, you can determine the overall cubic inches of your engine. In this video, I show you how to do this process with basic measuring tools, a little bit of time, and a little bit of practical math. Engine building can be fun, but there is some science involved with it. I have been learning from a skilled machinist and every engine build I am part of, I try to learn more. The two pistons used in this video for demonstration purposes are both Chevy small blocks. One is a 283 that will use Keith Black hypereutectic pistons, and the other pistons are from forged from Sealed Power for a 302. Making horsepower sure is a blast!

Those KB hyper pistons don't like getting hot before a run down the 1/4. Lots of math but a good way to double check you got what you ordered.

Ideally, room temp for tools and the part(keep them together) is 68° for at least 12 hours. Hold yer measure tool as little as possible, and only on the plastic insulator (black thing), especially on the standard you are checking yer tool against. For clearances of . 0005 inch (one half thousandth) or less, this is a must. Unless you have passed away recently, you are radiating almost 100° !!

you are 100% correct! Was talking to my son today about the temperature changes and how that cat change things. I think I am still 98.6, ha!

@2HacksGarage measuring consistently to a millionth of an inch makes everything else look like child's play! 👍

I think it is because of the odd compression height
