New member to the forum, although I have been lurking, for a few months. I bought a '51 Plymouth Concord back in June. It has a '54 Plymouth 230 (I learned from this site). The car is lowered 4" all the way around. It has been a bit of a struggle, since I bought it, but I think I have her running alright. I chased a midrange stutter for a while, and I found that I had low compression in #4 cylinder. Pulled the head, and didn't find anything. I pulled the valve covers, and discovered a broken intake valve spring. Replaced the spring, buttoned her up, and was left with the same problem. Pulled it all apart (this time with the K-D 700 valve spring tool) and found that the intake valve was bent. Lapped in a new valve, and put it all back together. I think she will hold up, for the rest of the season. Won't be doing a whole of driving in these miserable Midwest winters.
