Hi good video and correctly done 👍 I would like you to express your views/ opinions on ported and manifold vacuum please as I’m about to fit a vacuum advance unit to one of my cars that didn’t have one fitted to it in 1938 the year of manufacture, now I’m confused because there seems to be a right good argument on TH-cam about it ! ie some saying ported and other saying manifold????
Use ported for the best performance of the motor. However, I also build distributor curves knowing that I will be using ported vacuum. If your distributor was designed for manifold, then use manifold.

Good video. It was a question i had after the last video, what good looked like. Thanks
I think this motor may have had total seal piston rings which is why it was so good. A normal motor would have 5% or so.
