I'm going to convert my carbed 540 over to EFI this winter and am taking a serious look at the new Holley HP EFI setup. One nice feature of the system is it's ability to drive multiple coils and use a crank trigger to eliminate my MSD box and distributor. I would also likely use a cam plug with sync so I can go with sequential fueling and timing rather than waste spark.

Has anyone here converted a non-LS to multiple coil system? What coils did you use? Would standard factory or MSD LS style coils work fine? I would have to come up with a decent way to mount them near the head which will be a pain. Is there really much advantage over the twin tower coil waste fire setup that Holley uses as a default?

The other option is to use a dual sync distributor to do sequential fueling and just stick with the 6AL2 box I already have to simplify and save some cost. Is the stability of the crank trigger worth it? I still get timing control with the ECU that way.
