Default Question about Cloyes timing chain

To run a Cloyes timing chain I would have to convert to a EWP, remove the waterpump drive, and remove the CPS reluctor. Is that all that needs to be done for clearencing for a 96 camaro?

Also, on the summitracing web site, they list 4 different chains; CLO-9-3145, CLO-9-3145-10, CLO-9-3145-5, and CLO-9-3145-15. Which one would I want to use?

You'll just need the 3145 unless you've had your block line honed. I had to run the 3145-10 since mine was...

Why would that be?

Because line honing the block reduces the distance between the crank and cam, therefore a shorter chain is needed...Usually around 0.010-0.015" shorter.

Interesting... mine was line honed and I'm using a standard length Cloyes double roller... fits fine w/ no noticeable slack.

Well, let me rephrase that...It MIGHT change the distance between the cam and crank, depending on how much material had to be removed in order to do the job.

^^^^ Yea you would talk to the machine shop and ask them what chain would be best in relation to material taken off.

Ed,
That is a nice looking piece for a very reasonable price. I have been looking for a good DBL-roller that I can just plug & play. It looks like your saying the unit does not require any additional work with the stock 96/97 timing cover. I don't want to modify my cover, just want to install it and go

Some have to, some don't. Mine had more slack than I was comfortable with.

I installed the same cloyes set on mine ( 95 LT1) and i had to modify my cover ...
tried without gasket : no clearance
tried with two gaskets : still no clearance
I had to grind down all the cover reinforcement that is around the opti hole so that the cam gear section would clear .... now i have around .045 clearance ...better be safe then sorry!

Both of mine have 1996/1997 timing covers, no clearance problems with either. Cleared with no gasket before assembly. The 383" has been run three or four years, the 355" all last summer. Have them both apart right now, no problems. If anything ever touched it would be evident. Maybe the OBD2 cover has more room? Don't own an OBD1 cover, so can't say.

It has more adjustment than the Cloyes, and a Torington-style bearing on the back of the cam gear, so no wear on the block, both gears are billet, not cast. Made in Austrailia, very nice setup.

Ed,
Thanks for the product endorsement I went ahead and purchased the item. I will definitely say it's very nice for $95.
