Joe, would you mind sharing the specs on the forged pistons you ordered from JE? I'm in the process of trying to get my pistons ordered and would like a reference. If for competitive reasons you're unable to I understand. thanks! 55blacktie (2/2/2022)
Joe, does that include forged flat-tops/w no valve reliefs and metric rings for EBU and C2 rods? Thanks. Because there were some questions regarding piston ordering asked in a different and somewhat unrelated thread, I have started this post specific to ‘Custom Pistons’. When ordering custom pistons, the piston rings are the first consideration and are ordered prior to ordering the pistons. Piston rings are not available as an ‘off the shelf’ item for every possible bore size so the bore size must be determined first. Depending upon the availability, it may be necessary to juggle the bore size in order to get the ring width sizes you are looking for. Because of the many small bore metric sized pistons that are available, there are a number of cylinder bore size options but these may not fall in the normal 0.020, 0.030, 0.040” sizes that are typical to the American engines. In some cases, the final bore size may fall into ranges between those numbers. When the rings are ordered, you will need the bore size, ring thickness, and radial depth numbers for those rings so that the pistons can be machined specifically for those rings. A word of caution about ring thickness. As the rings get thinner, the cylinder wall finish gets more critical.
