Best Timing Chain SBC 350 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Cloyes is one of the best, but from the link here, you can see all major cam manufacturers offer them also - all the way down to $29.99. I don't think billet gears are necessary for a street driven, stock truck - the main reason to get away from a "stock" chain is the neoprene teeth. So, really, any metal chain with steel/iron sprockets is an upgrade, and one that will last. Having said that, there IS a slight pecking order inside the double roller world also. Some double rollers are just basic double rollers (i.e. two rows) and then there are "true" rollers - they have links that are more like a bicycle chain that rotate also. I'd opt for a true roller personally, but, again - ANY all metal setup is an improvement over stock. It's also nice if the Torrington bearing is included (I think that's what it's called..) Personally, I think the extra slots for adv/ret are over-rated. If you're running a stock setup, that additional cost isn't really necessary - but many many of the chains out there have the three keyways. Doesn't hurt anything to have it, but not necessarily worth paying extra for if you're pretty stock. If you plan to degree the cam, it's a handy option depending on what you discover when doing so.

Which GM crate did you start with? I'd be surprised if it came with a neoprene chain unless is was the 190/260/290 Gen I version they sell. Those may have neoprene, not sure. How many miles have you put on this chain? 12 deg is huge...

Here's a fancy one if money is burning a hole in your pocket - includes hex-adjust and billet sprockets and torrington bearing. (Hex adjust is a small insert on the dowel pin (or something like that) that allows fine tuning of the cam. Not really necessary, but handy depending on your tuning comfort level.

As you can see, prices vary widely depending on cool factor and neat little gee whiz things. Basic works just fine. The base for me is the 2nd link above. But I sure like the last one too...

My recommendation as well. You just can't go wrong with a Cloyes true roller.
