I'm using the Ford coils that Bryan Blake references and I've seen his L-series Ford coil bracket in person - it's very nice. I'm using a Megasquirt MS3X ECU, a Nissan ignitor to drive the Ford coils, and the DIYAutotune optical wheel in my L28ET distributor. But, my engine is EFI (Nissan ECCS) to begin with.
First you need to decide how you want to drive the coil packs you want to use. There are many different ways to do COP but nearly all require an ECU (and $$$)… I'll be puzzled why you want to go this route on a carbureted engine.
You'll probably find the most information on this stuff at https://forums.hybridz.org/
(Okay now a little more: If you want full sequential you'll need both a cam and crank signal to "tell" the controller when the engine is approaching TDC on the compression stroke. You can do a wasted spark ignition with only a crank signal. Wasted spark will fire 2 coils at the same time since it doesn't "know" if the engine is approaching TDC on the compression or exhaust stroke. You still need a "spark controller". I think most people use a toothed wheel on the damper pulley for crank signal (toothed wheel and a sensor to "count" the teeth - a missing tooth verifies position). The L-series doesn't have a very convenient way to mount a cam sensor necessary for full sequential COP. Though many people have found ways other than using the L28ET distributor body and drive spindle. The '82-'83 280ZX Turbo (L28ET) uses an optical wheel inside the distributor body to provide crank and cam signal to it's ECU. Since it mounts on any L-series engine, it's pretty simple to use - costs money and is getting harder to find, but it's fairly simple. There are also other similar C.A.S. units that can be adapted (but that's not generally an option for a DIY install - you need skill and/or a machine shop and/or $$). And, that's just a start...)
