LS5 distributor
 

I was digging thru "stuff" on the shelves in the storage building, looking for left over '62 Impala parts to sell, and came across a loose distributor I have been looking for since I moved. It is the original distributor for my LS5 engine in the '66 Chevelle. I had a Mallory shutter wheel, electronic conversion on it for many years. Has a 526 CCW mechanical advance which I believe is still original. No clue where the vacuum advance went.
Build date seems rather early for a late January build engine ?
It's had '65 closed chamber heads on it since I bought the car in '73, so it's possible the O/O changed the distributor too.

That's a 1970 LS5 distributor Mitch and the earliest date I've seen on one.

Yep, forgot to mention it is a '70 LS5.
I have read mention of it, possibly, being for '70 L78 engines too ? Could be why it's an early build date and didn't get used in an L78 ?

I've had a couple of them. LS5 distributors, though they are not worth all that much are fairly hard to come by. Yours is definitely a legit stamp as well.

Dang, same date too.
Not looking to sell, just was happy to find it again. Rather certain the weights aren't original, as I had a re-curve kit in it. I should have it renewed, tuned and re-introduce it to the engine.
I still have the Mallory set up too, but I only seem to have half of the shutter wheel. No clue why they got separated and where it is. Hopefully, that will turn up in another box from moving.

Believe the 70 L78 got the 1112000 Dizzy
