My first time here, so be gentle please. I am trying to make road worthy my "Copper Kettle" '68, and need an exhaust for what appears to be a 340 someone before me swapped out for the 350 . Anyone recommend where I can look and get what I need? From the manifold on back is needed. Thank!!!!
Moses,
Here's a couple of pages from the 1979 AP Exhaust catalog showing a '68 350 system (diagram 327) and a '67 340 system (diagram 333). One piece will likely have to be modified or custom manufactured to get the 340 crossover pipe to fit up to the 350 intermediate pipe.
The AP website shows the '68 350 parts to still be available, probably from a central warehouse location. The 340 crossover pipe does not show up there, but there may be other sources for it.
If there is doubt about the engine's identity, it can be confirmed by matching the ID codes stamped on the block to the 66-67 340 codes on the id section of this site. Hope this info helps.
