Yes, you're both correct as far as I know. Both the late TR6 PI and late Carb
models had the 311399 cam with specs below. The early TR6 PI cam (307689)
produced 150 BHP, and had timings of 35-65/65-35 and 0.375" lift.
Hope that helps,

Is that when the PI power dropped from 150 to 125?

Looks like the late PI and USA carb engines have the same cam? Or is this a
typo?
