Here are three 2 minute videos of our 1960 GMC. The 1st one was taken a while back on the old 20+ year old motor. It isn’t very interesting until about 1:37 into the video:
This one is on the new 350 crate engine with a Comp Cams HE268 & Pete Jackson noisy gear drive idling:
The latest is just showing off the new Doug’s electric exhaust cutouts in varying stages of closed and open. They are partially open in the beginning, and then go to full open. I kept the revs down as it's easy to blow out the microphone on my cheap little camera.
