5.7 0r 6.1 with msd hemi 6 and carb

I also went to the extreme as to pull the whole front of the motor apart to make sure the timing chain/marks were correct trying to find why,Also had one of the top tuners here in Wisconsin drove 5 hrs to help us with a timing curve for this motor and made several curves we loaded in the hemi-6 to try result---THE MORE TIMING WE GAVE IT THE MORE IT LOVED IT Steve
