Well, this thread inspired me to buy a Burtz engine. I love driving my 1931 Victoria and while it has a perfectly good "diamond B" block, being able to "future proof" my car with a Burtz engine has been something I've wanted to do for a long time.
I plan to keep my car as close to Judging Standards as possible, so this Burtz will serve as the foundation for all "correct" additional parts. I also bought an Aeries muffler yesterday. I figured as long as things are going to be torn apart for the engine swap, might as well change that out too.
I don't know what the tariffs will do, or if they will have any effect, but I needed a push to finally buy one and this was enough of a push for me.
