New Timing set options?

[tejohnson]

Thought this may interest some of you:

Todd, as far as I know there are two types of V6 engine.
V6 Semi Even flat tappet 200-229 cu.inch, which would be p/n CS1000.
V6 Even Fire Flat Tappet 262 cu.inch, which would be p/n CS1000 again.
V6 Even Fire hydraulic roller cam followers Factory that would be p/n CS1020.

From my understanding, these are exactly the same timing sets used in the V8?s

The last number is a TPI timing set that has a thrust plate and reduced nose on the camshaft and a smaller register on the cam sprocket.

Go to my web site listed for more options.

Secondly, while there click onto my US Distributors button and call one of them for service.

Subject: Timing set for Chevy 60° V6

Hello,

I am curious if you have anything for the Chevy 60° V6 engine. The 2.8,
3.1, 3.4, 3100, & 3400 all have the same centerlines. I am aware that
Cloyes sells a double rocker timing set, and it would fit, however, it
is for the 2.8 & 3.1 engines, which is a higher profile. I was told of
a company in Australia whom makes a lower profile double roller timing
set. Would you happen to be that company? If not, do you offer
anything at all for these engines? Thanks in advance!

Regards,

Todd E. Johnson

Any thoughts?

Yea lots. They are all for a 4.3L V6. None will fit a 660 and that guy is wrong. Only the oddfire and semi even fire and even fire before 1992 are the same as a V8. All V6's with a balance shaft starting in 1992 are unique timing sets.

Grrrr.... Alrighty then. Are there any alternatives to stock besides the Cloyes double roller? Reason I ask, *not to put him on the spot*... Brad seemed to have issues with his. Givin that I would have to grind the cover, I wanna be sure it will hold up...

Reason I thought I was on the right track was due to a conversation with a Cloyes tech whom mentioned a lower profile timing set that was imported from AU. He may have mentioned the name, but I can't recall that lil detail from about 4 months ago ( cause I figured I would go with a cloyes double roller )

someone out there must have a dual roller for us-- i hope

[geoffinbc]

Take your dual rollers and shove it. A silent chain will stretch less and out live a double roller.

[torq455]

so i'll advance the cam 4 degrees. besides, isn't there HP to gain off of the roller?

ahahahahahahaaaahahahaaHA! Yeah right.. I used to go through a stock timing chain and gear set every year due to stretch!

[torq455]

geez! what kind of valve springs you have in there, and what RPM do you run to? that's good to know. quess i'll just replace the stock chain every year.

[TurboZ24]

I've had no issues with my roller chain on mine, it's lasted through a lot of powerful valve springs. My current ones are 198 closed, 460 open and so far, it's not stretched. I'd like too see a stock silent link do that.

I've machined the cam sprocket and the crank nose too allow the double roller too fit under the stock cover with no mods, and modified a SBC needle bearing thrust button too fit.

[geoffinbc]

That because a GOOD roller timing set will be pre stretched

But a silent link will still stretch less over its life than a roller chain. Colin if you were goin through chains every year something was going on there.

[torq455]

something missaligned maybe?

[v6h.o.]

Well they were not GM chains. they were melling units. Which should be able to take it.

LS1 valve springs are not at all stiff. Just my abusive driving habbits Is all that I could ever come up with. No alignment problems. Chains would go on perfectly fine and would then come off with chewed teeth and stretched chains.

Chewed teeth Wow not cool. Were actual chunks missing? I drive pretty abusive too. I have my engine to 6000 at least once a day. If Im racing every gear change is at 6000 and I always powershift. My chain is mint. The Melling unit may be to blame. My springs are about equivalent to your LS1 springs aswell. I also run 1.6 rockers.

Colin, what RPM do you redline at?
