I have 10 miles and a short break-in on my stroked 351. I bailed on the Holley and went with a edelbrock 750cfm. After getting the timing , idle mixture set and idle rpm set.
On my short test hops. I notice it crackles or short backfire sounding noise. I think it sound great.
My buddy thinks its running rich? so the excess fuel is making the cracking noise on throttle lifts. It has ton of power and accelerate very strong. I haven't check the spark plug color yet. What does your sound like after running hard through two gear shifts and lifting off the accelerator? Should I be concerned?
