I'll throw my 2 cents in. You're not gonna add power to that slant (or really anything) as long as the point type ignition is in GOOD SHAPE.
So, why not learn the points system, discover how it works, learn to tune it. Get it in good condition. Points have been around for a hundred years in millions of vehicles.
In all honesty, electronic ignitions ain't "much" of an upgrade from a good workin points ignition.
That way, you actually learn somethin, fix "WHAT'S THERE" and spend less money.
I don't know.......sounds pretty good to me.
