8 1/4 will get u going some of that depends on pipe and prop but that is a good start point

Alex,

What elevation are you running at?

 

[alex poca]

250 feet

 

[John Knight]

At 250' elevation, you should be able to get at 8" or even shorter. The engine really does not turn on really well until you get to 8" or shorter. I am at sea level and mine is 7 5/8" but I have a 7 port. Give it a try but richen it up slightly. Testing is the only way to know.
