Heavy Z Posted August 19, 2003 Share Posted August 19, 2003 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! 327, 9.5:1 comp T5 transmission performer RPM heads Comp XE-268H cam super victor-style manifold Holley 650 DP Hooker blockhugger headers Quote Link to comment Share on other sites More sharing options...
Heavy Z Posted August 19, 2003 Author Share Posted August 19, 2003 I just found a couple of Grumpyvettes articles on timing, great info in those archives! It looks like the stock springs are too heavy and that all advance in by 2800-3200 is a good place to start. I'll try it out tomorrow.
