I'm also used to seeing Broadhead's 60 Pontiac.

But, see Boyce's book pg47, it shows Broadhead's 66 olds 442 running C/S at the Winternationals etc, says he "hopped out" of his usual 60 Pontiac.
The 442 ran in the C/S=9.50 class that year.
So that part makes some sense to me.

What does NOT make sense is the 66 Winternationals sheets show Broadhead running D/S=10.60 class in a 66 Olds. I'm thinking maybe THAT was his 60 Pontiac? Ran both cars at the same meet?

Back on the Records sheet - I have Hamilton's car as a 4dr sedan Starchief
3826+100)/330 = 11.90, perfect fit to class (adding 100 lb for the big hydramatic battleship anchor).
Boyce says it was a 338hp FI engine, but that won't fit class, the car is then too light, (3826+100)/338=11.62.
I'm thinking the 338hp combo came later in 1968-up when there was an 11.50 class, which is then a good fit.
Any recollections there?
