Install was easy, nice and noisy. Less than a thousand miles later its broken. Washers on one of the idler gears split open and dropped into my oil pan. Thankfully no serious damage. Will not being buying from them again.

Does not fit a ford 302. No matter how much you grind the thrust bearing down. On top of that you have to do fabrication work to your timing cover. My best advice is to buy a double roller timing chain an for get this garbage. But on a good side the shipping was great.
