[PJS50]

Thank you Scott for that insightful explanation..
Coupled with what I thought I already understood regarding this issue, I feel MUCH more enlightened now....
My "local" guy suggested that I run a max. advance of about 36 degrees with the intial reading to fall somewhere around the 16 degree mark. I plan on recurving my MSD this winter to do this and fit a new Mighty Demon 850 to the manifold at the same time.
Just losing the air horn should take care of a lot of my airflow issues that I believe I am currently suffering from. Let alone, I am ditching a pretty poor carb that was selected by the previous owner...
I just have to make sure of my hood clearances and I will probably go the Demon route too...
Thanks again guys....
Pat
