Rebuilding my Y at the moment with a Y block in a Box kit from John M and have a nice 1963 NOS distributor that I was going to fit a Petronix ignition to, How would this compare to a Mallory unilite, what is the advantage or disadvantage of each or would both give a similar result with performance.

All comments welcomed.
