I finally found the 1969 Indy Nationals results in Drag News.
I sure can believe those CCJ heads were in play.
In Super Stock, for each class, a 1st, 2nd, and 3rd (alternate) are listed.
The 428CJ (or, 428CCJ) ran in 4 classes stick and 4 classes auto, G=8.50, H=9.00, I=9.50, and J=10.00.
So there are 12 possible places for a 1-2-3 finish in each of 4 classes.
Of those, the 428CJ took:
11 of 12 SS/stick spots
10 of 12 SS/Auto spots
Class wins in the 4 classes the 428CJ could run in":
3 of 4 SS/stick classes (A rarely seen 327/275hp Chevy II took the SS/J=10.00 class)
4 of 4 SS/auto classes (A sweep)
This is in contrast to the Feb 68 Pomona debut where, for all the bally-hoo, the new 428CJ only took one class.
Something sure changed.
Would anyone know which of these cars had production line heads, C8OE-N etc, and which had the magic CCJ heads?
I hope these attachments of the results come through ok. Even the LWG made a cameo appearance as R/U in SS/D=7.00 class, with the HiRiser factored to 500hp.
