Belt sizing help please

[1968Droptop]

I currently have belt size 1600-8GMT (Gates). I'm adding an intercooler, which is 4" thick. So I need a belt that's 8" longer (right ?). What size will that be ? I looked on BDS's site, but they only list belt sizes for small block Fords :mad:

Hope this helps
To find the proper belt for your application, you must know the following:
The make and model of the engine
The style of pulleys (1/2 pitch, 8mm etc.)
The total tooth count of both pulleys
The center to center distance between the upper and lower blower pulley
If you do not have a complete standard BDS blower system, you will need to measure the center to center distance from the drive snout on the blower to the crankshaft of the engine. Look at the Belt Chart to find a measurement that comes closest to your measurement. If you cannot decide which belt will work for your application, we suggest calling our tech Department.
Locate your engine and belt style in the chart below. The chart will find a total teeth range for a specific belt length.
