re Arnie Toftland:
Do you know for sure it was a 71 LeMans?
I can get 2 cars to fit that I/SA=11.00 class:
71 LeMans hardtop 455/325 auto only (non-ram-air?)
3575/325=11.00
71 GTO convertible 455/335HO ram air
3717/335=11.10

It looks like Wheeler was the runner-up in I/SA=11.00 at 71 Indy, here's a picture, looks like a ram air convertible ie GTO:

But, are you sure which combo Arnie Toftland ran?

I don't have a clue. Lots of '71 racers used a 455HO T-37. Rock Running ran the 1st one I was aware of. Don Turk has it now. Scott Underhill held the E/SA nat record with his, a few years back.

The car in that pic is not a Pontiac. Looks like maybe an Olds. I suppose it could be a Buick. I'm not that familiar with either.

Just Googled it. A '71 Cutlass Supreme SX has the long scoops.

442 also has the long scoops, but looks to have deeply recessed grills.
