I will check and see, I know someone in FL who had a 350/350 that he only wanted $150 bux for. I was looking for my vette but it was too far away.
That said, I have several 350 cores (all in need of rebuild) but shipping would cost more than they are worth (should be able to get a 350 core at any boneyard/engine rebuilder for $150-200)
You looking for a performer or performer RPM- with or without EGR? I know of a couple people with them...
(I have a three vehicles with 350's in 'em so I'm always on the lookout)
