I just dyno'ed my motor yesterday at an engine builders shop I used to use, it was built by someone else ( long story ) the owner told me the industry is a mess, he can't get parts and when he can its a long wait. The recent buyouts and consolidations are making things even worse. I guess I was lucky I was able to get everything I have needed recently with no problem , my engine builder was able to get everything needed for my build also. I do see things on parts websites with delivery dates a few months away. I am tempted to buy a new set of the drag radials I use just to have them.
