THANKS for the quick reply guys !

Next question.

I'm real interested in Ryan Schloe's car. He was once claiming a '71 Bird, with a #66 head 455.

Lots of guys on some of the Pontiac forums really badmouth those #66 heads. But since Ryan ran below 11.50 with his #66 head 455, maybe they're not that bad.

I know that Adam Davis' '71 Bird was switched over to a '73, so it could run a 4X head 455. At Indy 2017, he was #74 @ 1.023 under.

Most all the numbers look better for the '73 4X head 455. Especially the 306hp factor. Means Ryan can run a lighter car.

Just did some checking. It seems that Ryan switched over to the 4X head '73, a few years back. Best ET I could find was an 11.04. So, if he hasn't dipped into the 10's yet, he's come close.
