In ‘97, having recently completed a turbo L28 in my ‘72 240, I drove Braap’s newly completed 12 sec. SBC 280Z. While my turbo project was very underdeveloped, I enjoyed the ‘simplicity’ of the SBC. I decided, nearly overnight, to build an LT1/T56 Z. Three months later, the 240 morphed into the following...

Unfortunatly, this Z was built some time ago... mistakes made, lessons learned, memories faded, and pictures lost... sigh.

 

I owned this Z longer than any other. It underwent various changes, most with an autocross focus. A few for cosmetics sake. This Z helped drag home many trophies and FTD’s.

 

Sadly, she no longer exists. It was parted out to start a machine shop... RIP.
