One of the things I am planning when I finally get around to the head swap in my car was getting weaker springs. With the way the engine is tuned right now I can't really get the engine to redline anyway the top end is totally weak. I get the best power shifting at 3500 so if I find a set of springs that will float at 3750 I am set
I have a pile of Metro springs sitting around I just have never measured one to see what size they are so I know what to order to replace them. If it ever gets warm here I might get out there and work on something.
