That is interesting.... in most cases it seems to make a difference. What’s the Venturi size and throttle bore size on the 4150?
Throttle bore is 1-3/4" Not sure on the venturi size
I just found on the web if it's correct........1.45 venturi
Interesting..... of course I’m running VP C12 fuel, but my 1050 seemed to wake my car up quite a bit from a 1.48 Venturi 1.79 4825 Braswell (4150 based) carb.... just wish I hadn’t swapped the 727 to the 904 at the same time so I could really tell how much.
