double roller or single roller timing chains?
Ok I've been given both sides of the story here, and of course I'm just going to get more opinions, BUT which is better, single or double roller? In my experience I've never had anything but good luck with single rollers, so why switch now? but last night a buddy told he'd never tear one down with out putting a double roller back in. What is ya''s opinions?

Single rollers suck, double rollers suck, at least get a true roller or a gear drive if you are going to upgrade. I don't think double rollers are much better than single, and you get what you pay for. If you want a decent roller at a budget price get a Cloyes "Street True Roller" which has a true roller chain, but less than bullet-proof gears.

O.K. - I'll be the first to admit I'm no expert, and rely on second hand info a lot, but I'm ready to learn something and would like to know the reasoning behind your statement, and will start off by providing mine. Double rollers are just that- 2 stock roller timing chains compressed into one and subject to all the same stretch problems as one, ( although a little more solid, due to the 2to 1 factor). True rollers not only have twice the rollers, they actually "roll" reducing wear and freeing up a little friction in the process, and are more reliable and have more longevity than double rollers and don't cost much more. Gear drives are deadly accurate in the timing department(zero stretch), and are stronger than chains.

I did install a gear drive that sucked once. Did not think it was possible til then. The kid wanted to hear the gears and bought a "Noisy" cheap gear set. Let the cam move 6.5 degrees. Pain to dial the cam in and it did no better than a chain at holding the cam. wtf??? So maybe just cheap gear drives suck... lol

They built it loose to be "extra" noisy. Since it was sold as a feature, I am sure they sacrificed performance for the noise. The big value of gears is to hold the cam true. Agressive cam ramps and higher spring pressures will factor more than RPM to needing gears vs a chain.

+1 for the Cloyes true street roller.
