I got a 6a MSD box and wires. This is going with a HEI ignition. I need to buy a external coil, and external coil cap for the distributor correct? Am I missing anything here? :confused:

No disrespect here at all but unless you race regularly and are in high RPM's MSD boxes really arnt neccesary for the street. GM HEI's with vacuum advance that are rebuilt with some basic upgrades are not only ultra reliable and rev high but bullet proof to boot. You will get a wide variety of opinions on this subject

My 2 cents

You don't "need" to. A 6AL can be wired to the factory in cap coil if desired.
