I used a lead additive when I got my 55 Plymouth. It has a 6 cylinder in it. I would put a few ounces to a tank full of gas. Quite easy. Well my engine decided to take a brake and I had to pull it out and have it rebuilt. The top 2 rings broke on #6 piston broke and didn,to want to compress any more. When the engine rebuilder tore the engine down, I told him to replace the valve seats with hardened seats. After he got into it, he found that the seats were hardened seats from the factory so he didn't have to change them. He did find that all the top rings were broken. So now were bored .030 and it runs very nice now. That job was done 2 years ago. The engine had about 41,000 original miles on it. It now has about 47,000 on it now. And I use high test in it being I don,t drive it so much. On June 11 in Olean, NY the Great Race will be comming thru and there will be a car show, I just called for some info on it, You may check out the web site at ---www.greatrace.com--- I also have some Firestone wide whites on her but I can,t remember the width of the white walls. Dave, my manuel for the 55 Plymouth says 24 lbs pressure in my tires. If you have an owners manuel or shop manuel for your 58 it should say in there about yoour tire pressure.
