Bests & Worsts Reviews from Amazon

Very nice quality and packaging, so far no issues with the sputtering issues I constantly had, hopefully no more cap and rotor replacement every 6 months! UPDATE Still running perfect!!! My advice as far as replacing and installing if you're not familiar with engine repair is to watch some Y tube video about the installation process and especially the lining up of the gears to get it to fall back into place. Take a picture of your distributor before you take the cap off and again after you remove the cap, to make note of the position of the rotor inside of the cap and the direction it is pointing, you are going to drop the new distributor in and match the direction the old one was sitting. The gears are cut at an angle so just before you drop it all the way down you will have the rotor slightly pointing off of where it needs to be pointing, as you wiggle and drop it the rest of the way down the gears will make it line up. It might take a couple tries to get the distributor shaft flange to seat flush, just take it slow and you should get it. Also, AT NO POINT SHOULD YOU TURN THE IGNITION TO HELP IT DROP IN. The Vortec engine is a electronic timing and as long as you get it in like the old one was positioned it will run perfectly! This engine is not like the old engines that you would use a timing light, the Vortec will automatically set the timing as long as the new distributor sets in the same orientation as the old one. Again watch some videos if this doesn't make sense and take your time.
