has any one installed or know of anyone using a late model efi tb42 electronic dizzy and coil rather than using the Pertronix conversion on the old tb42 is this possible and does it have its advantages

not possible. the EFI dizzy has a fixed shaft and doesn't directly drive the coil.
Leave the pertronics at the shop and let some other fool waste money on the unreliable voltage sensitive bits of shit.
Spend the extra and get a Crane XR3000 kit with a PROPER 12V coil

I have had the Petronix for over 2 years without a drama. Car is stock so all I desired in the conversion was to ditch the points for ever.

they don't run with low battery voltage. We had one at work on an MG, it would start and run with points, it would not start with the pertronics. how ever if you got a second battery jumped it straight to the ignition system it would start and run with the pertronics.
put a crane XR kit in it and it would start and run with out a problem on the same battery that would not start the pertronics.
Good luck push or tow starting with a dead battery in an emergency.
I also don't see the point in 'upgrading' the ignition and keeping a low out put 9V system. Then people will go out and buy extended rotors to help fix the weak ignition. Kill two birds with one stone and fit an XR3000 and 12V coil.

been running the petronix for almost 3 years, and one of those its been used as the trigger for a crane hi6s ignition module with an msd digital coil, made a massive difference, more free revving and smoother!
