Ok, so I've got two engines...

Engine 1:
Ford Pinto 2.1
Twin 40's
All the normal 'hot' Pinto mods
Ignition = Distributor + Bosch ignition module

Engine 2:
Vauxhall 20XE
Twin 45's
Stronger bottom end and increased rev limit
4 branch manifold
Will be putting some hairier cams and probably replacement lifters in
Ignition = aftermarket elecontric distributor, single coilpack + hall effect sensor.

At the moment I'm happy running big 'ol thirsty carbs, but have toyed with the idea of tb's for the XE in the future. I'd really like to get rid of the distributors on both engines and go with a more modern dizzy-less and multiple coil-pack setup and also get the best out of what I've got with a mappable ignition system (apart from a Manta distributor, the XE ignition setup is about the simplest we could have fitted)

Megasquirt & Spark seems to fit the bill as the info indicates that it can run multiple coil packs without a distributor, if you have a ford 36 tooth trigger - I guess the Pinto already will, as it's an ex Sierra injection unit, stripped of the injection system... the Vauxhall has the crank trigger in the side of the block (which we managed to keep from damaging!)... but I'm not sure whether that would work for the MS&S system - could a Ford trigger wheel be fitted to the bottom pulley?

Basically thinking that moving to the MS&S setup for ignition only at the moment will let us get the last few % we can from the engines with the carbs - but give us the scope for fitting injection/tb's at a later date.... plus get rid of those nasty distributors (I'm already on the second on on the Vauxhall engine - the supplier I got the system from isn't around any more either!)

Anyone else gone this way?
