Hello all... it's been a few years. Just wanted to check in, and see about a timing set. What brand double roller is everyone using?

 

I have the SA Gear set in my truck. (about 40 something bucks at advance.) Others have used the Cloyes, or Comp cams gearsets. So far, I haven't heard of anyone having trouble with any of them. After all, how do you screw up a gear set?

Nice to see you again.

 

I was originally looking for a comp set, but had a heck of a time finding an application search (why I posted). After looking around, I think i'm leaning towards Cloyes street true set number 91103. Thanks for the heads up

 

Comp cams and Cloyes are good ones. I bought the Mopar Performance originally and surprised I didn't bend a push rod because the timing marks are different on the Mopar Performance. The Cloyes and Comp Cams have the correct timing marks.

 

Hey You suggested a Double Roller Chain with a .25 chain pitch . Found one at auto zone. I did mine today and when I got into my engine there wasnt even a tensioner on it. Curious about that......The new chain doesnt require one....

 

I have the Mopar Performance timing set as well. The timing marks on the crank gear are stupid, it has a very large dot on it (which is not the one to use), and a tiny little dot that you can barely even see (use this one). Just be very careful when using this timing set.

 

I think only the six cylinder engines came with the chain tensioner stock... No clue why. I did not install one on mine when I changed it.

 

Don't have a tensioner on mine either... with a good chain, you don't need one... with a stretched chain, there would be an advantage, but you're moving to a double row chain to avoid that (stretching chain).
A tensioner will increase friction and may slightly effect power and mpg numbers... it may also increase noise a little.
With a bigger cam there maybe more need, but I'm not sure... any of you guys with the 408 Stroker use a tensioner?

 

I wouldn't add a tensioner. I added one when I did mine and when I tore back into that part of my motor a few months ago the double roller chain had scored groves in the tension brackets which are plastic. If you go reading a bit the tensioners are only really designed for single roller chains. I also had the Mopar Performance like a said above and I didn't like the timing marks. For the purpose of just OCD hopefully in about a week I will be tearing back into it again to do the plenum and I will be replacing the Mopar chain with a Comp Cams which I am VERY pleased with. The marks are easy to read and its a 100% USA made chain. Looks very well made and I'll be removing the tensioner and putting the original thrust plate back.

 

I tore apart an LA that had a tensioner, As dodgefan99 said the plastic guide and metal behind it was worn into by the chain. Don't use them.
