Bud, not to add fuel to the fire but the clutches have ink stamped dates and some have month and Year stamped on the flange. Do yours have any of these??

I know this is not your year, but my 70 Z28 original fan clutch has Eaton CV K1J it's a 04B car. Have no idea what K1J stands for or how to decode it.

What would be the correct clutch for a 1970 Camaro SS-L78 and would the date be prior to
the engine build or the car. The engine in my L78 was built over 6 months before the car.
This whole date code matching when doing a restoration is tricky. I would love to see an
Original Survivor 70 Camaro SS L78 so we could document a lot of unanswered questions.

"What would be the correct clutch for a 1970 Camaro SS-L78 and would the date be prior to the engine build or the car. The engine in my L78 was built over 6 months before the car."

I would use the Cars overall cowl tag build date as the reference point,not the engine Tona date.
Yours used Fan Clutch Part#3946050,same as the 1969 L-78 Camaro and Fan Blade #3947772.

I gave you misinformation earlier.
You should have Fan Blade #3789562 18" diameter 5 blades 4 bolt circle.
Sorry.
