It’s been a while since I was at Sonoma or Laguna watching the classics. I will be later this summer and I’m going to really check out the road race AAR and T/A’s while in the paddock. These were 340’s that were de-stroked to 302’s. Not sure if the cars ran a high volume water pump or larger radiator. Not seen a B.B. road race motor, but a race boat yeah and similar timing setup.
