How does one know what voltage is good for whatever type of ingition system they may have? I currently have the MP electronic conversion, with the chrome box. I am running the Accel Super Coil (the large one), installed on the firewall. I am considering purchasing a canister type coil to mount to the intake in the stock location, to clean up the engine bay a bit. I checked Summit's website, and there are numerous canister type coils with several voltage ratings to choose from. What would be a good choice for my application? this is for a 70 Duster with a 340, soon to have Edelbrock heads.

Thanks in advance!
