OK, I'.m looking to work on the curve. I saw this in the summit catalog. from past posts I know it can be done with springs and things. just what are the"User friendly" graphs ect. Ive got a PC I can use . I did a couple of searches and came up empty. I've got a 9.532something to one 225 + or - With an Offy manifold and a 600 Edlebrock.I'm replaceing worn out headers as soon as they get here.I've decided to install a bung for an oxygen senser MSD 8933, Mounted on my dash I think it will be "Green" and pay for It self in fuel savings, I was thinking about getting a MSD-8680 timing control to go with it but then I would like to keep my options open for future nos and/or boost retards.From what I've read curves can be varied on each cylinder independently with a MSD8979 /77,can this help equal out disimular mixes caused by intake manifolds .I know I could talk to a salesman but I would really like some unbiased opinions. Thanks Bruce J.
