The 71 Demon 340 I acquired recently was missing the kick down return rod spring. I put a universal one on it until I could get the correct replacement spring from Year One. When I tried to install the new correct one it would not fit because the attachment ear on the rod is too close to the front. I have a spare 1970 340 engine in storage and I pulled the kickdown rod off of it and put it beside the one on the Demon and could tell that it would work since the ear on it is about 2 inches further back. Does anyone have a pic of their kickdown return rod on a 340 engine to compare? In the photo you can see the difference in the one installed compared to the one I took off of the spare engine. I will test fit the rusty rod and then restore it. Should I sandblast it or would you soak it some kind of rust remover? What paint would I use on it?
