17P6 (and 17P12) are 'high power' coils.

So would an m6 and a p6 coil be compatible wired in series on a Lucas Rita set up? As i am using this at the moment and have a problem with it cutting out on one cylinder when under load ? Cheers

I don't know. Possibly.
Is it always the same cylinder that cuts out?
If it is, have you tried swapping the coils/leads/plug caps/plugs?

Baz,
I used a tool similar to this to show a bad coil. I also think if you can use an induction timing light to pickup an intermittent spark.
