Re: Update ignition?
Well, if you are talking about a larger older Chrysler engine with distributor, points, and coil, then yes the upgrade to CDI is relatively easy--if you have the parts. Buying them new would be prohibitive so you would need to scrounge up used parts. But in all likelyhood you will not see an increase in performance. True, the pointless ignition is a bit more precise in timing but you still need the distributor--and the distributor needs a special shaft and electric eye.
If you want to go distributor-less, then you need a different flywheel, trigger, stator, Trigger and stator mount (which requires drilling and tapping 5 holes ) plus the CD modules and coils.
A lot of fuss for a very little return. If your engine is running well with no ignition issues, stay with what you have.
Remember, automobiles had points and coil ignition up to the 1970s and ran very well.
