According to Barney Gaylord, the "MGA Guru", a four-cylinder has no
need of additional dwell (or even as much as Lucas gave it) unless it
is going to be hitting stratospheric RPMs. The Mallory dual-point
distributor in a four-cylinder is more about a higher degree of
precision in this application. IMHO, all the more reason to install
the Pertronix module for it.
