Hey, I've got a double roller timing chain from melling i believe got just a few thousand miles on it. At present, I just swapped my cam, and when i bolted the timing chain back up, there's some slack in it, fresh rebuild going on a couple thousand miles (maybe 4000 at most) and i wanted more power so i put in a newer lunati cam grind....

It's a 350 bored .030 compression at 9.34-1 cranking is 165 psi (yea the cam has a pretty late closing intake valve), all the parts checked out fine on the topside...however...

If i remember correctly, that chain is supposed to be tight, and it's currently got a good couple degrees of play.

is it just a case of pos defective part? that's what i'm banking on, but then who do i go through for a new double roller timing chain?

thanks for the input
