Now my problem is that it's calibrated for 4 or 8 cylinders and I have a V6 305. There is a calibration sticker on it, and using the ratios listed, I think it will display correctly if I get the pickup end of things correct. On the sticker it says for 8 cylinders and mag pickup "180T", which I interepted as putting two pickups 180 degrees apart? Under 4 cylinders it says "90T", so I'm thinking that for a 6 cylinder could I put 3 pickups 120 degrees apart??? Can I get the magnetic pickup at NAPA??? Should I just chuck this sucker in the dumpster and start over?? Thanks in advance  Scott :confused: | | |
