So, my 67 took its maiden voyage this weekend. Just had carb send off and rebuilt, new wiring harness installed, and few other items added. Couple trips around the block, couple hill climbs on the back of the proprty, and then a spirited drive down the road. All fine and good. Later on Sunday I drove my normal drive to work. Roughly 5 miles in and I hear knocking (uh oh) then I pull into a parking lot and hear a loud squeal then the truck jerks and I shut it off. Look around pop the hood and there is a small amount of smoke coming from the entry hole on top of the motor. Let everything settle and cool down before I try to get back home. About a mile in loud squeal and engine shuts off. It won’t restart and I get a tow home. This morning I go out to truck and it starts and runs with the knocking g still there. Any ideas of what I messed up???
I also have a video of noise but can’t post to forum.
