Electrical question

[RDelany999@aol.com]

I'm new to the list, have a '74 MGB chrome bumper, and close to closing on a
'53 TD.  I live in Bucks County, PA

Iwould like to know if anyone has experience with changing the coil
to a high performance (40,000V) one.  Does it make a difference?
What are the negatives associated with increasing the voltage?
I am gettting the MGB ready for the road (Spring fever) and am thinking of
changing the coil if it really does make a difference.

Any experience welcome!
