Well after years of searching, I have finally been able to track down some photos of my Z when it was a race car. I am delighted, to say the least.
It also allowed me to learn more about the car's race history; it was bought new in late June 1969 and began to run at Lions Dragstrip. By early January 1971, when the photos below were shot by photographers for Hot Rod magazine, the car was still the original silver with black stripes, but had some dark (probably black) infills added down both sides, plus race decals and lettering, in addition to the Cragar S/S wheels. The flat hood appears to have had the hinges removed, as it sits high at the cowl, and there is an interesting curved tube in front of the driver, probably a tach or a fuel pressure gauge.
Note the original California black front plate (the username I chose when I signed up here years ago - as I got both original plates with the car), the Clippinger Covina plate frame (which backs up the NCRS Shipper info) and the VE3 front bumper still on it today.
These photos are from the 1971 AHRA Grand American series at Long Beach (Lions) CA and the car ran in the Formula Stock class.
Some time after January, but still during 1971, the car had a full repaint by renowned pinstriper Bob Kovacs in Fresno, and ended up switching to E/MP class, presumably under IHRA or NHRA rules. I'm not sure at what point the hood was cut out, or when it was mini-tubbed for wider rear rubber, but that is how I bought it. The car's name also changed from 'Fiasco' in 1971 to 'Home-Grown Fiasco' when it was repainted. The home-grown part could be a reference to the owner's father and son auto parts business in LA at the time.
The copyright and ownership of the photos below must be credited to TEN (The Enthusiast Network) and the Petersen Publishing/SEMA Digitization Project. I have made contact with them to seek access to the hi-res and non-watermarked versions of these, but have not yet heard back. In the meantime, I hope it is OK to post the publicly-available Lo-res versions, along with an acknowledgement of copyright.
Just wanted to share my delight at finding these pictures with the many friends I have made on this forum!
