Went to the datsun meet here in Santa Rosa, 1 hr north of
San Francisco. Quite a number of 510's, some roadsters, a
late 50's pickup, and of course the Z's.

One 240Z was sporting a VG-T with over 300+hp - didn't look to see if crank or at the wheels. Another Z was fitted with a Chevy 350 (aka Scarab).

And a 510 with a VG30 from an 85 Z. overall, pretty neat little meet/swapmeet.
