Timing question
I have an internally stock 2.7. On top I have 40mm PMOs, MSD6AL ignition and a JB Racing 6 plug distributor.
Im trying to tune this thing to perfection and I have a question.
Yesterday I used my LM2 and adjusted the AFR to about 12.9. Now I am trying to find the perfect timing spot.
The distributor was purchased and set up by Steve at Rennsport. I am not sure what the advance is but it comes on fully by 3500 rpms.
When I set the timing at 3500 or above and shoot for 32 it settles back down to 13 BTDC. Doesn't that seem high for an idle timing mark?
If I do what PMO says and set the timing between 6 and 8. It only gets up to about 25BTDC.
What is better? A closer to TDC idle timing or closer to 32 at 3500 RPMs.
All in all in runs pretty good, just trying to find the elusive 'sweet' spot.
