Well, I just rang Tom, who seems like a nice bloke (albeit, with a bad stutter) asked him a few questions a bout the 240z.
He has a reserve of about 10g ( i think that may be a bit high).
The car has an aftermarket cam shaft which he described as very lumpy.
The passenger side floor pan has had rust before which he had welded and glassed in the past.
No rust in the battery tray apparently.
Most gauges work (most of the time, clock is dodgy and oil pressure can be intermittent.
It is what I want, and off to a nice start (with the cam and simmons) but I am not sure if 10g is too much (still new to the scene guys), anyone got any opinions on this?
