    Rated 5 out of 5 by from What a bargain! After the HEI in my El Camino died, I decided that I would just buy a new one as a replacement. A friend recommended a Jegs unit. When I opened the box I was amazed at how nice it was. The parts are well made and sturdy. I am very happy with this purchase, and would do it again.

    How many degrees does the vacuum advance add and would using it void the warranty on the 260hp crate I got from y'all?

    Asked by: C10trucker
    You should be able to get about 30 degrees of total advance from this distributor. As long as you use the correct distributor gear on your engine based on the camshaft, this will not void the warranty. If it is a GM engine a dealer will need to install the distributor.
