Good news! I was able to file-fit all piston rings and get them installed on the pistons. I also measured all rod bearing clearances and was able to determine that we are in good shape with all rod bearings. We are at 0.0035 with all of them. That is exactly where we want to be [...]

Spent some time this evening getting ready to measure rod bearing clearances. I was only actually able to figure out which rod/piston combo will go in each cylinder. I measured the big end of every rod and found that they were all at 0.985 except for one which was 0.982 and another that was at [...]

Just a quick update about the engine development progress. Worked on installing the Spirolox in every piston. This meant that I only did one side – so a total of 16 spirolox rings were installed. I made sure to install them only on the side of the piston with etching (just for consistency) and I [...]

I still want to weigh the pins. And after I get rod bearings installed, plan to do a gross weight analysis but with the intention of getting every pair almost identical in weight here is how the pairing works out so far: Cylinder Piston Rod Weight 1. D D 1257.4 2. E A 1257.4 3. [...]

Piston Weights A. 448.1 B. 448.2 C. 448.1 D. 447.1 E. 447.4 F. 448.4 G. 447.7 H. 448.6 Statistical Analysis: Mean: 447.95 Median: 448.1 Mode: 448.1 Range: 1.5 I was very impressed with this set of pistons. They are a set of Ross Racing Pistons (http://www.rosspistons.com) and I feel like they were an extremely good [...]
