Hi, just checking HP threads, what carb would you add with a Synder 6:1 head. This engine has 2k miles on it from it's complete rebuild. thanks!

I like the way mine runs with a Tillotson. It is my only experience, so it could be mediocre in reality.

Either a Stromberg 81 or 97 or the Weber that is commonly used today. I once ran the Auburn hill climb in my '30 tudor. I had run it first with a stock B engine with stock A carb. A few months later I changed to a Winfield 6:1 head, the time was a full second quicker up the hill. That same day I switched to a Stromberg 81, times were almost another second quicker. The next time I ran that hill I had changed to a 97 carb, times were 3/10s of a second quicker. I love to experiment like that. That car got really quick when I installed my 4-port Riley in it!
