    Rated 5 out of 5 by from Great Buy I have a 1968 Chevelle that was running a points system. I purchased this distributor in attempt to relieve some frustration with timing issues. I also had to purchase "GM HEI Power & Tach Feed Wires 12" Wire Leads" for the old wiring setup and my after market tach. Ripped the motor down, set it to TDC and dropped this baby in. Started right up, and sounded beautiful. You can not beat it for the price and to get things running right. Also, this item was delivered faster than expected. I received it a full 4 days before the expected delivery. Way to to Jegs.

    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.
