Hey,
If your rebuilding your 454, and decide to put a double chain timing chain set in, be aware, you will also need a new timing cover. The recessing on the OE cover hits the large gear. Edlebrock makes an aluminum cover, part number 4241 aluminum timing cover. It works perfectly with the wider gear set. And it's shiney, and lightweight too. A little pricey too. 79.00. DJ
