Timing Chains
I have pulled the pan off of my 460, and the timing chain has a little bit of slack if you poke it from the side. Does this mean it is stretched? And if so, what would be the best replacement for it?

It can be used if it has very little slack in it. If you have to replace it, then I would go with a double roller chain. Or you could go with timing gears, but not sure if their available for the 460.

I would say that very little is acceptable. How much do you have from pulled back to pushed foward? (total slack in other words) You can get away with a little and different books call for different amounts, but I generall won't use anything more than about 1/8"-3/16" total slack. Some people will use them with more, but I prefer to use them wih even less.

Another reason to just go ahead and put a double roller on it is that they are MUCH MUCH less prone to "stretch" as well as they wills et your timing straight up instead of retarded as some of the factory sets are made to do.
Go ahead and drop the $40 or so if you can spare it. Your truck will thanks you.

My poor opinnion is unless race Straight up cam time unless you "have" to run EGR. If not then as stated straight up with 38* total with the dizz or less, advance till ping and back off. Check out Cloyes web site and look at thier selection and engineering guide. They have wild sets with multiple keyways and some that are fully adjustable if your into it. Good luck.

I usually run cams straight up on a street engine, with a few exceptions. I think puttin git in straight up with a double roller would be as good a setup as you're gonna get on an otherwise stock engine. It'll pep the low end if you have a factory retarded cam timing and the added power will come with some improvement in economy as well.
