Stock 302

For this page I've been looking to find some pages that just talk about the care and feeding of a stock 302/289 in a Bronco. I know the old timing chains with the fiber gears were definately not a "Better Idea" and are prone to go since mine did in my '77. When I tore open the motor, I saw lot's of wear to the valve train, the cam, the rockers, the valve seats, etc. The crank was OK but the pistons were not in very good shape. And this was on a motor I had recently driven back from Colorado to Michigan -- 1200 miles at 75MPH cruising.

I would guess most origional motors have similar problems. If anybody knows of info on what to watch out for, what to replace and generally how to keep these old motors happy, suggest it in the box at the bottom of the page.
