Thanks, eEd.

I wan`t to raise my exhaust port on one of my P5 offroad engines, power is already quite on off but i have changed timing on crankshaft to open a little erlyer 5 degrees. It was smoother alrady then.

I will now try to get some moore revs on top and open 5-7 degrees on exhaust port. I am just experimenting, only way to leran
