Thanks Squeeze...
I'll take a look at the carb. If it isn't a 1 barrel like the Prev Owner said, is there a particular model PCV valve you'd recommend? Also, since the draft tube is large (@ 1 1/8") is it normal to reduce the feed to the carb that much? This is all new to me...
As per your first reply, the engine sounds, idles and runs great! Some backfiring when changing gears but since I just got the old truck, I would like to have a good tuneup done but I wanted to take care of the Road Tube first.

Thanks again for the pix and arrow!
