I'm somewhat new to this group, only posted a few times. I traded for this 1979 620 std cab truck back in Sept 2012. I want to put it back to better than new condition. well, improved a little bit I guess. It has been worked on by the same guy for over 10 years and he has already changed quite a bit from the factory. It's L20b has already been bored .040" over, a new Weber 32/36 was installed, a NISMO cam was installed (260 duration, 420 lift) with a cam wash system added too. I'm told it has a performance clutch/pressure plate and flywheel. He said it now has 280Z front calipers installed for better braking. 2" exhaust from the manifold back. the factory fan has been removed and an electric installed with a toggle switch on the dash lower edge. It actually doesn't run hot with the fan off, we'll see what summer in NGA brings. Here are a few photos before I started improving it:
