What else do I need for a complete ignition system that is for my 383 LT1? So far I am lookin at getting:

MSD billet distributor
MSD 6AL box
MSD blaster coil
MSD plug wires

What else do I need to complete ignition system or is that it?

Also, what spark plugs do I use? What determines the gap to use? My engine is a 383 LT1 with ported heads and intake - can someone point me in the right direction in picking spark plugs or what is the gap I should use and why?

Thanks

Use standard application copper plugs. Anything else is a waste of money.

Do you mean an MSD Optispark, or will you be running some kind of conversion that uses a distributor??

Yea, its the opti but on various websites they just title the part a distributor...
