engine question
I got this 454 from a guy who said when he got it it was supposed to be a fresh rebuild but they had flattened a lobe on the cam. so I tore it apart today to replace cam, lifters,timing chain, intake, and carb. blah! blah! blah! and the inside was very very clean. and I couldnt find any metal in the oil or anything. but when I took the cam out it had 7 yes 7 flat lobes, crushed lifters/ and bent pushrods. what in the world causes this as I have never seen anything like it before.
also arent the dots on the timing chain gears supposed to be lined up when the #1 piston is at tdc?
