Pontiac’s Trophy 4 came in the Pontiac Tempest and was literally half of a 389 V8. People that love them are weird, but dedicated. If you ever saw one running in a Tempest you would laugh when it was shut off. They run fine, and are perfectly acceptable for that light little car, but if you watch one when it is shut off you’ll know that I’m right when I saw that they look like your dog shaking after a bath. This thing shakes as it shuts off and is just strange.
But Richard Holdener got his hands on one, that ends up not being a runner because of no compression. So can he fix it? Or is it going to need an actual rebuild?
