The # will tell you the size in 32nds of an inch. A 33 is 1 1/32"

450 venturi is a #29 meaning it is .906" If you ask 5 different people what size you should run you will get 5 different answers. Every tractor is different. Only way to get it just right is to take the time and figure out what she likes by boring it out on a lathe and testing. Or, if you want to take a shortcut you have the following options:

#29- 400-450-and some 460"s
#30- 6 cyl, 263ci
#33- 6 cyl-291-and some 301"s
#35- 301 (715 motor)
