Looking for a Ignition CM for my 1974 2.7l engine. I see the MSD 6201 Digital 6A on pelican and I am wondering if i'll run into any issues with that, and also what else would I need?

QUOTE(Cfletch @ Jun 9 2015, 09:36 AM)  I think I'll go with that unit I mentioned. Do you have the coil part number? And with the cd and the new coil I should be ok as far as ignition correct? Why? Why would you not want to take advantage of having a soft rev limiter? Just wait until you over shift and are replacing values and doing a top end on your 2.7. you might wished bought one that had that feature. (IMG:style_emoticons/default/dry.gif) You can have issues with the sparkplug wires, and as mentioned you could have issues with the tach working correctly if you use a VDO. |

Because according to Mark the model mentioned has a limiter. |

Model 6201 I don't see a mention of a rev limiter. QUOTE(MJHanna @ Jun 9 2015, 08:37 AM) Why? Why would you not want to take advantage of having a soft rev limiter?

In a real bad missed shift a rev limiter is NOT going to save you, as that is a mechanical over rev. In the same vane you should never use a rev limiter as a shift indicator. I don't care if they call it a "soft" limiter you are still loading and unloading the engine at high RPM. A rev limiter is a safety device, but never think it's fool proof. |

So with the 6al and that shock proof coil I should be complete? Still running a vdo gauge |
