Not legal in NHRA but legal in AHRA.
Some of the 1967 Yenko 427 Super Camaros were built with a drag racing package including headers, scatter shield, traction bars , hood pins, tach and gauges, and high temp plug wires.
This is well documented on the original Yenko work orders.
Yenko and Harrell sponsored a 4 car drag racing team for 1967 only.
In 1969 the COPO 427 Camaro was legal for NHRA Super Stock and Yenko sponsored two Daytona Yellow Yenko 427 Camaros.
Don and Dick Williams knew they had to make a good showing in that Super Stock magazine drag test.
They took the Gold demo car to York set up with headers, scatter shield, 4:56 gears and Atlas mag wheels.
I don't think it was a coincidence that Ed Hedrick Bill Jenkins , Dave Strickler, and Jere Stahl were at York for the testing that day.
Jere installed a set of his spring clamps and a set of header collector extensions.
Ed bolted on a set of his slicks.
This PA. crew was "loaded for bear" and they pulled off an amazing 11.94 ET at 115mph
"Mission Accomplished"

Could you ask for a better dream team a coupe tricks they used at the time in stock classes was to create a vac leak and jet up for it effectively adding CFM , some would even rock the carb up at full throttle to add air this is why stock class cars were notorious for revving the crap out of the engine before pulling to the line to clear the loaded up engines / plugs
They would also on camaro and firebird loosen the top nut 1 inch on the front shocks to give it 1 inch of travel before having any resistance even with drag shocks .
Another was to file / grind the serrations off the bushings in the front end to give it an easier weight tranfer.
