Did they have to track down leaded gas? Did they just use unleaded? Did they suffer engine knock?

    You could also convert cars by putting harder valve seats in, not sure if this happened a lot at the time, or whether it’s more for classic cars that are worth enough to make sense to do. I don’t think the lead was primarily an anti knock additive, more of a valve and bore lubricant

      Getting hardened seats isn’t really all that expensive either. I took the head off my MG and a shop only charged me about $300 for a full teardown and rebuild of the head, including all the machining and installation of hardened seats. It’s way cheaper in the long run than having to add a lead substitute every fill-up
