Thanks Lynn, and everyone for the opinions,
Yes the chambered is a little louder, what are the specs on the 178, I wanted to stay away from the .030/.030 because the lifter were too noisy to suit me, I had them set at .026/.026, still noisy, so I decided to try the 140.
one thing I noticed with this 140 cam, my automatic choke works great,,but even at cold startup this cam wants air before the choke is warmed up to open, I am going to adjust the choke so it isn't closed so tight.
