Guys that is most definitely a dent, the previous owner said as much! So, Charlie, what's the deal with the pipe?
Still talking the Pat, he would rather sell the whole set, instead of piecing them out. He wants $350 and shipping for the whole set...
I saw another set, they looked identical, but had some white stick marking that said 350 on them. The only thing is, they didn't use those pipes on a 350-4... so, I am thinking they are not marked correctly... it used to happen a lot back in the day. I am going to pull down the upper right one and look at it, and see if it is good. They didn't look too bad, but are hard to get to. Have to wade through a lot of pipes to get to where they hang. Will let you know as soon as I find out, though!
