318 I'm assuming. If the intake has the way larger 360 ports just get the right intake gasket set. What carb? Set the timing marks at 15 BTDC on #1 compression with the magnet dead even with the tooth that places the cap terminal with the #1 wire over the the rotor. You'll need a 4 pin generic Mopar 4 pin ECU from your parts house (A standard Motor Products LX101 is the best if they carry it) & a ballast of ~1 ohm or a bit more & the wireing diagrams are in the archives. I think you can reuse your coil. Holler back if more detail needed. EDIT if you have a 4 terminal ballast parallel wire it along with a 4 pin ECU & you're good. (add a blue loop of wire at the other end of the ballast so both ends have a blue loop of wire)
