Hello all, I've got a question about my MSD distributer. How do I know what RPM all my timing should come in on my 327? The stock springs on the dizzy has it all coming in by 4,000 rpms, but there are lighter spring combos to bring this down to 3,800, 3,200, or 2,400 if you want. Any recommendations? Any advantages or drawbacks to timing coming in earlier? I thought I'd ask before I do some test runs as I'd like to understand this a little better first.
Thanks!
