I've used Mallory Unilite distributor - which works fine doesn't look stock though. Could probably pick up performance with the Mallory box. I like chrome box and mopar distributor all right running 2 like that now. I have a 440 with MSD occasional use starts up runs good without a choke. I liked small block dual point and hated points with old slant six cars. You might want to
figure out a good hiding spot for the MSD. Inside the car away from engine heat. Actually that would be a good idea for the chrome box also lol.
