The best timing gear setup for heavy use. Don't care about the price.
What do you think is the strongest timing gear setup for a lot of beating on the rev limiter and race use.
Double or single row chain? gears?
Chain damper?
Using the Melling 296 oil pump.

ATI damper and for the chain invest in cloyes gears with a C5R chain.
A good single row is better than a off brand double roller.
Cloyes sells a good product. I toured their factory back around 2007 and looked into some of the QA and automation work they were doing with 3 axis robotic arms. I actually have a cloyes set in my engine.
The type and brand of crank damper does play a large role in preventing chain breakage, as Tuskyz28 said. A chain dampener also plays a role, especially in a road racing motor or any engine that experiences engine braking and de-acceleration followed by getting back on the throttle. I bought a Trick Flow dampener adapter (TFS-K30675600) and LS2 dampener that I will be installing with my timing set. I bought a Avon Progear PG4210 timing set for my LS1. It does not have the trick Cloyes Hex-a-Just advance mechanism but KCS told me once that it (hex) can get crushed and need replacement. I believe Progear has the best gears on the market. Hardened billet upper & lower, one piece lower, tumbled before & after hardening, concentric and accurate. Gears made to last. The Progear set uses the Rolon chain. I believe this chain is almost as good as the IWIS HD chain, which is to say, it is NOT the best on the market. That distinction belongs to the IRL chain that coSPEED2 mentioned. Next up would be the C7R or C5R chains made by IWIS. All these are single chains and should work behind the Melling 296 without front cover modification.
The rolon chains are normals for cloyes. The iwis chain comes in 2 varieties. The std which is better than the reg rolons etc and the c5r or Z chain. The reg iwis chain comes on the hd gearsets from Rollmaster which also make quite a few lesser known gear sets. The Rollmaster gears have the same treatment as the progear you allude to. cloyes has 2 different types of gear setups. they are both very nice and in reg and hex a just setups. the main difference is ease and range of adjustability.
for the ultimate chain, the irl chain is it but is SUPER hard to get ahold of esp in small quantities.
i think i have some pics of the gm ls2 vs std iwis vs irl chain somewhere...

Is the IWIS one you speak of the 3sr60-2 https://ls1tech.com/forums/parts-cla...ing-chain.html
I'd like to know what the difference between it and the c7r that Hinson sells is? Both are seamless rollers and according to the bar graph stronger than the c5r chain.
I'd love for cloyes to release the matched IRL timing sets again.

He said cost was no option 
JESEL BELT DRIVE
Want to make power? Use a belt. Significantly more expensive, and even more expensive to maintain, but also reduces valvetrain harmonics to almost nothing, and takes abuse well.

I'd do the Cloyes Race Billet with the Z Chain or the Rollmaster Gold Series Double Roller (what I have). It uses an IWIS chain with nitrided billet gears.
I would definitely do adjustable billet gears - they are worth it to dial in the cam for your combo.
If the IRL chain were available through Cloyes, that would win, hands down. The set would be well over $300 though.

I have sold them before. I know. At one point they were listed at nearly $600 and people STILL wanted them.
The issue with double rollers is the install. Spacing and grinding and shimming etc.
Most cam installers wont know the intricacies of using an adjustable timing set but most aftermarket sets are adjustable to some extent. Some like the cloyes hex a just are quite a bit more adjustable.
