The DUI works way better than the stock ignition on my AMC 360 V-8. One of the best engine mods I have made. Ignition is all in one unit. Replacement parts are common.
You have to properly clock the distributor when you install it because there is not a lot of adjustment space to correctly set the timing. The HEI distributor is big and makes contact with other engine components if not installed properly.
Bottom Line:
The DUI ignition is one of the best mods I have made to my AMC 360 V-8. It runs crisper and seems to make more torque down low. The ingested fuel seems to burn more completely.
