Big Money and no need for the street imo

I never said it was cheap or for street use.

this is kind of off topic, but is there any benefit to buying a timing chain with billet steel gears vs. iron gears?

The billet steel gear timing chains are more expensive and look better, but is there really any benefit? How often do you break a timing gear? I have never seen that happen, I have seen chains let go but what difference does it make if the gear is billet steel or iron?

Well they look cooler!! and youll know that its in there. You could always take a picture of it and then show people!! LOL! Really though I couldnt say that theres much benefit Only thing i can say is that this rollmaster set comes with "Chain is German IWIS chain, the finest in the world."
I bought one because i wanted the highest quality set made. I felt this was it.

Unless you like the whine... like me! It's great pulling slowly into a car show... keeping it in first with the RPMs up... everybody stops what they're doing to see what's coming.

I guess it is all a matter of taste and if it is a more accurate way to keep the timing , then I guess I could put up with the whine . What the hey !!!

Thanks for all the options . This being made to be a weekend toy (small block) I think I will put up with the cool sound of the whine . I am adaptring a shaker scoop from Australia (boss 302 ) style to the car so it should have a lot of people guessing as to what's going on under the hood . Thanks to all for the help and can hardly wait till the snow melts in April to get back at her in Winnipeg Canada here . good luck to all !!!![img]/forums/images/smiles/icon_tup.gif[/img]

There are some rather successful custom cam grinders that seem to sing the praises of this product. Seems word on the street is that it's the king of the hill as far as chains go.[img]/forums/images/smiles/icon_tup.gif[/img]

Talked to one builder who would only use gear driven. His only reason was that he felt it was a safety factor (for the pistons hitting the valves not safey of the driver).

The new Hyvo chains and gears that the Roush team are using in NAscar are a big improvement over the stock chain. We have been switching these into our mountian Snowmobiles and have eliminated chain failers.

ummm Nascar uses Timing Belts must be because those chains give them an unfair advantage or something, also I would not believe any test in any of the car mags out now a days because its all paid for by advertisers
