Hi Al , welcome !!! I joined the club and there are alot of GREAT people here. I have an original Van Nuys built '70 SS. It is totally original under the hood,except for plugs and plug wires, fuel line, and a vaccumn line or two(and battery,alternator). Valve covers have never been off. The carb is a 7040200. I'll get you some detailed pic's under there, but it may take a while, the weather sucks and I don't have alot of time on my hands right now. There is NO and I mean NO,"0", zilch , emissions on my car even though it is California built! That is, except for the PCV valve and heat risor, LOL. I don't know why, maybe because it was built in '69. I have the build sheet and I am 3rd owner. Second owner sold the car new in 1970 to the original owner. Give me a little time and I will get some pics to you. Scott.
