Is that date known for when the CE code was first stamped on a block? I see some articles say 1967 and others say 1968

1968 427 Yenkos had a tag in the door jam. 
also some 68 COPO Yenko Camaros were sold as SS396 not converted to 427

R68GTO , you can drill two holes in your stick and use it as a bolt on for an aftermarket Hurst Shifter.

I bought a lot of shifters in the 1980s and 90s just to use the stick on aftermarket Hurst Shifters.

back then a worn out OEM shifter was cheap at the swap meets but the round Hurst stick was popular to convert to a bolt on.

Same thing with the 67-68 Muncie shifter. I used to buy them and convert to a bolt on for aftermarket Hurst Shifters

Yenko used two local fiberglass companies to make parts for him. One company's main business was fiberglass bath tubs and shower stalls.

Yenko had fiberglass hoods, deck lids, seats, spoilers and other parts made to his design

Yenko, and probably others back in the day, would use their racing buddies to get parts and services as many racers were business owners and raced more as a hobby.

I have a set of prototype fiberglass side pipe covers Yenko had made for 67-69 Camaros. They are too thin and have cracking so didn't go into production.  here is the receipt

an early use of the rear spoiler was the 1966 Yenko Stinger fiberglass rear deck lid

not a normal production car but is recognized by FIA and SCCA as a two seat sports car manufactured by Yenko Sports Car Inc .  Jerry Thompson was the 1967 SCCA D/P Champion in a Stinger

In 1968 "Bunkie" Knudsen left Chevy and went to Ford. He took Larry Shinoda and Smokey Yunick with him.
Bunkie left Ford in Sep 69.

Don Yenko bought one of the Yunick 68 Camaros and it won the Citrus 250 at Daytona in 1969. Warren D., who was on the Yenko team, said they had a lot of trouble getting it through tech :)

Sometimes a car would be marked as "scrap" but then sent to a shop to use for parts or a race car build or test car.

not sure how much of this story is true but this 1970 Camaro is said to be a pilot car , then test car , then sat at Smokey Yunick's shop for 20yrs

In his book, Yunick said he was given pre production cars to build his NASCAR Chevelles

are you running stock distributor set up?

I would look at the distributor vacuum advance  assuming your mechanical advance is working correctly

a lot of tuning can be done with the vacuum advance unit.

If you search on it , should find info on running ported vacuum vs non ported vacuum

The amount of advance is sometimes too high on a stock vacuum advance unit

I made plates for the vacuum advance unit where I can limit the amount of vacuum advance you get from the stock unit

this was the caption for that photo...

"This scene was recorded on the front lawn of Phelps Chevrolet “Eastern Carolina’s Volume Dealer” located in Greenville, NC. The press photo was taken by a photographer from the Greenville “Daily Reflector” apparently for a year-end clearance sale held on August 1-3, 1967. In the line-up, visible here are seven Camaro’s four of which are Super Sport models and the third from the far end is a Rally Sport.

1967 was the beginning of production for the all-new Camaro, Chevrolet’s new offering that was under development since the early-1960s and rushed into production to compete with the Ford Mustang. The first examples were on sale in the showrooms in September of 1966 and available as the standard model, the Rally Sport (RS), the Super Sport (SS,) and later in the model year the Z/28 was introduced. A wide range of engines was obtainable including six-cylinders and V-8s in sizes all the way from 250 c.i. to 396 c.i."
