In some instances, technology can be both a good thing and a bad thing. In the case of installation instructions, YouTube is your friend. Written instructions, even when we read them–which is never–isn’t as fun nor as educational as seeing a certain action performed in person. These days, you can YouTube almost anything and get educated in the process.

Diamond Pistons’ chamber mold kit is a two-part product used to come up with combustion chamber size, compression ratio, and valve sizes to help the company design the perfect piston for your engine.
Diamond Pistons sees the benefits of posting many of its products and processes on its website and on YouTube so everyone can be educated on the best way to accomplish a particular action on their own. The above video is to properly show how to make a combustion chamber mold.
A combustion chamber mold kit reproduces an impression of your engine’s combustion chamber. This kit is designed to provide all the information a piston manufacturer needs to make a piston to your exact application. The mold kit provides the “fingerprint” of your combustion chamber’s layout and your cylinder head’s valves. The chamber mold kit can also compute the chamber’s cubic centimeters and your engine’s compression ratio.
Diamond’s combustion chamber mold kit, as explained and demonstrated on a small block Chevy, is inexpensive and easy-to-use, but it will go a long way in making sure you have the right pistons for your combination.
