Trying to put things together, reviewing old posts Doc wrote ...........I may as well add a photo of the JP Performance timing chain set.
All steel gears with multi keyways on a heat treated lower gear. It is a true roller type chain. Cox has these imported from down under, they are made in australia......

He then wrote........The Cox Boys also carry the cast iron double row "roller" chain, that one works well for a mild performance build-up and it is a little cheaper.

For all-out racing, the JP Performance steel gears and multi keyways is the way to go.............

I am not going for all out performance, I am however going to prob. be putting more stress and strain on this engine because of vehicle weight and inertia needed to get it moving so I am guessing that the ...............Cox Boys also carry the cast iron double row "roller" chain, that one works well for a mild performance build-up and it is a little cheaper...............would work for me but does it have the multiple key-ways that I may need to get cam dialed in properly? Do I need this feature?

Still trying to figure out all this multiple key-way mumbo jumbo but Ill get it

BTW napa has a double roller timing chain in stock locally for 21.99 part # 9168, did not have the gears, would have to special order them at about 100 dollars plus freight.

I look on JP Performance Timing Chain site and they have JP 5613 to suit 170, 198 L6, 225 slant six but offer no price that I can nor a description.

Can you guys educate me on what would be best for my application and why in dummied down terms when it comes to keyways and why the heck I would need all this extra adjustment......is it because the factory set-ups are so sloppily manufactured that in order to get the cam/crank dialed in MOST EFFICIENTLY I need these extra key-ways?

Thats what I am thinking at this point from what I have been reading and trying to understand.

I was also able to find in an archived post this info..........FWIW, the chain and the crank gear is the same as a B/RB. For some reason the slant double roller cam gear is available separately. The big block chain and gears and a slant cam gear costs less than a slant setup. Go figure................

Is this a fact, and would this be a better way or getting what I needed for a better price?

There are ways to do this if you want a double roller chain:

You can check e-bay and see the price for a rollmaster set a one option for $$$...

Another is to part one together from your local auto shop SA gear uses the old cloyes numbers :s338 cam sprocket, s339 crank, c168 chain should be a little less expensive...

If on the "cheap" you can use your current set up and redrill it for the bushing on the opposite side of the gear...

2 cents,

Yes the numbers you gave are the same numbers I had shown in the original post I believe so I understand that as an option but what about the other options I had mentioned, are they no longer existent? I know those were pretty old posts that I had mentioned.

Thanks

Personally, I think a double roller is over kill, and wasted money, on a mild build. Whether you use a high dollar set or a budget set, you should still degree the cam in.

I'm not positive, but knowing how "frugal" (cheap) I am, I think all my current engines have stock type timing sets.

PS: I don't think SA Gear has any double roller cam gears available. Cloyes might still have a few left from the group buy.

It will depend on who's boxing them up, looks like the Cloyes cam gear is available at about $52, the crankgear and chain seem to be more common and available at some local stores.

I do agree with charlie, I only use the double roller in my stuff because I'm hard on it (6000 rpm clutch dumps)...if I were doing a moderate engine that's daily driving or towing and i had a stocker set laying around I'd use it and move along...

You might want to get your current set up running, then plan another build on what you have learned and get your hands on it, then swap it in later on.

I am not certain of this ( come to think of it a quick look in my manual would verify ) but I think that the slant trucks in my weight class originally came with double roller originally. I have read this somewhere.

Id like to put back what was original.

Also doing a quick on-line search I found that the S.A Gear company is Discount Auto Parts $#!+ and at the top of the page is nothing but complaints about the gears not lining up properly.

I am going to look into the Cloyes, thanks for the tip

After a talk with Dave yesterday, the JP was the cause of his chain failure on the wagon. Upon closer inspection, he found that the gears did not line up correctly. He had to face the gear in his lathe to get proper alignment.
Probably should check alignment with any installation. I know I will from this day forward.

Im going to get a quality timing set, Im not even going to fool around with the garbage thats installed in there now, a quick on-line search of SA gear and right at the top of Google page very first thing is people negative experiences with these sets.

I only initially wanted to do this once but I certainly dont want to be doing this a 3rd time.
