Anyone have a good formula to figure out port durations???

 

 

To much math to figer out port durations with measerments do your self a favor and buy a degree wheel much easier.

Ok, so where's a good place to pick one up?? Will the 11" ones from Summit racing work ok, I was woried about a way to mount it to the crankshaft. It would still be nice to have a formula to work with.
