D.U.I. Ignition and HEI for 67-72 trucks

[dan468]

What is everyone's opinion on DUI HEI distributors? There web site is pretty sweet; type in your engine info and presto, custom tuned spark and good prices too boot. Also, to change to a HEI ignition I was told to eliminate the factory resistor wire on the lead to the distributor which will make the supply 12-volt. I did that and everything works fine, however, I'd like to know if everything is up to full potential.

Thanks in advance for all responses!!!!
