Originally posted to see feedback on a 3D creation, this text reveals a drawing done in 2003 by the author, who was younger at that time. The individual shares their thoughts on narrow valve angles and fancy pistons, and mentions an assertion by LKJ Setright about optimal cylinder capacity per engine. The author states they may have quoted Setright's statement verbatim from memory but admits it could be possible they didn't. This nostalgic post is signed off by Andy.
