I just did a google search for ZL1 carbs, and everyone I found has a choke plate, including some 3000 dollar plus restoration and original carbs.
Where is the info that they had no chokes?

I was reading an article about the #1 & #2 zl1s getting delivered of the truck and they couldn't get them started because it was cold outside and there was no choke. But you're right, after doing more research there was a choke plate but apparently it wasn't hooked up from the factory. It's tough to get legitimate info on some of that stuff. Sometimes it seems it's easier to get info on older cars from people on here instead of Google.

Regarding Carbs and chokes----All 1967-69 Camaro with Holley carbs had automatic chokes that are controlled by a thermostatic coil located either on the intake manifold or on the exhaust manifold ---THe EXCEPTION to this is the ZL-1 which had no choke----The early ZL-1 cars were produced with Holley 4346 and were later retrofitted at Gibbs with the 4296 carbs. The 4346 is the correct carb for 1969 396/375 & 427/435 engines---the Chevy part number and ID number for a 4346 carb is 3959164--- the Chevy part number & ID number for a 4296 carb is 3955205---my 2 cents
As far as spoilers go I ran a 1967 in Modified Production F/MP with ONLY the front spoiler never was questioned about not having a rear spoiler that car would always high MPH and it would out MPH by 1 1/2 to 2 MPH using the same exact engine in a 64 Corvette with the same driver . Coincidence perhaps? But I thought it looked kinda cool anyway---sold the car with the spoiler on it and the new buyer left it on last I ever saw it. FED 387
