    40506 is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Helped my idle quality Bought this distributor because I was having an issue with the idle quality on my big block put the distributor in and literally had to do zero adjustments probably need to mess with the vac advance a little bit because it has too much advance on the ported side of the carburetor so I unhooked it and it works great. I would highly recommend this if you’re needing to fix idle quality.

    Rated 5 out of 5 by from Really happy with this distributor Excellent upgrade from the stock style distributor. I like that I can use the affordable factory cap and rotor yet have fully adjustable mechanical and vacuum advance. Time will tell how well it holds up, but initially it's rock steady and works well with my MSD ignition. Great price as well...
