Removed the plugs and they look similar and are dark brown color. Years ago I did have a crank trigger ignition and forgot the plugs gap were set at .025, these are reset at .040. Lost the coil wire and bought a new 7mm one and after reexamining the coil end found that it did not go in enough. I think there was a coil resistor that came with the coil, but lost that also. So I modified the coil terminal so it now has a solid contact. Will test this to see if this caused the timing problem.
Had the car over 30 years and was converted to a V8, then L6 turbo and now going back to stock. Just about done with this project and hope to get it running and up for sale.
