Triple carburetors; looks like a whole lot of back and forth there to get it right. ;D
My dad drove a super modified during the late 50s and early 60s. He and his friend (salvage yard owner) rebuilt the engine every weekend (’48 Ford flathead, V8, maybe?). If I remember correctly, the valve adjustments had to be done from the side—little easier on his car (no wheel wells or fenders) but more difficult on stock cars (through the wheel well, if I remember correctly). I was very small but fascinated back then and asked Dad about it years later.
It’s funny how we can find pictures of super modifieds on the Net, but they’re all pretty with curves. The were pretty hot rods, when they first appeared on a track. They didn’t really stay that way for long, though. Not long at all, before they were reduced to only wearing flat sheets of sheet metal here and there. Boxy looking things but really fast...and really dangerous.
The truck was in the family since new and I started messing with it while I was in high school to get it running again. So, over the next 10 years or so would tinker with it enough to fire up then drive it a bit around a field. Eventually I ended up with the truck through inheritance then hauled it around as my career had me moving around the US.
It came time to turn the truck over to someone that could put in the time and resources for a proper restoration and sold it to a volunteer fire department in West Texas.. Their crew restored it to a show truck to use in local parades. I was happy and they were happy.
