There are at least 3 Copo cars known to have been ordered with V75. I would reason to think this option would have been thoroughly sought out & tested for traction control given how many cars were purposely bought for drag racing back in the day?
This Z/28 was shown a few weeks ago where it earned a top 5 pick with Best Muscle Car privileges the first time out. The best part of the show for me was the liquid tire chain discussions (had a NOS case of cans in the trunk thanks to Bruce) and of course the interior, which was a hit with so many. A few people had complimented how the restoration was totally on point for Day 2 and that it really fit the theme I was after. I found a lot of comfort in that, and the fact that even the local purists appreciated the way in which it was restored. A couple even kneeled down to peek under the car and came up commenting on the factory-correct paint application of the underside, as well as how correct the components were on the tricked-out rear suspension.
Here are a few more pics now that the car is finished up. Keep in mind that it varies from the purist side of things as I wasn't going for the factory-correct driveline with this car, although I do have
nearly everything to reinstate the stock Z/28 build should I change my preferences on that later. Piled up in my shop here, I have the original console w/ gauges, a rebuilt 3138 shifter, a full set of YH rallies with NOS caps and rings, and a stock DZ302 (dated V0214DZ) engine sitting off to the side that is 100% complete now. It's ready to swap into the car if I should tire of the current engine, but doubt that will be anytime soon (unless I decide to move the car along in its stock configuration).
Most of the interior is completely correct for this car except the NOS Super Shifter added for the period fit. I also forgot to install the moniker emblems on the door panels...so those will be installed whenever those panels come back off (lol). I did add a copy of the original V75 canister instructions and taped them to the deck lid during the show. The car as it sits is a total blast to drive and cruises really well at highway speeds in its current configuration. I should mention that it pulls extremely hard all the way through 7500 rpm and is not for the faint of heart. Finally, I have added a copy of the original invoice for this car which shows its original build details at the bottom of this post. :-)
For any other information on the car, its build, or the details of its prior ownership, there is a full build thread on the sYc site that is fast approaching 230,000 views to date
https://www.yenko.net/forum/showthread.php?t=161639. That thread offers full transparency of the cars build from the restoration of the body, the parts used to restore it, and some interesting anecdotes shared by previous caretakers as well as the car's original owner. As an interesting side note, this has been the quickest restoration I have ever performed (12-13 months) but definitely the most fun I have ever had restoring a Camaro (my fourth full restoration of a Z/28). Enjoy!
