When I start playing with the car again next month ,I'll crawl under there and get a date From what the original owner told me, he had it installed at the dealer before delivery.. Worked fine  when I disconnected it in place of a Mallory with a shift indicator/rev limiter. That was 1990 . The old SUN should be back in service this summer. I'm going to take a look today at the old SW gauges. Have the fuel for sure,90% sure on the oil pressure...plan on putting those back in service also.

Danny....You have my curiosity aroused, never thought about that dimple before.  My '68 has a dimple but it is only a 1/4" to the right from the line (balancer laying face down).  Maybe someone will have a logical answer.

Only dimple I have can be seen in a previous pic.....about 52 degrees. Nothing on the outer surface like dan's---plus there are some variations. For balancing purposes guessing ? I have a couple 400 ones I took a look at, externally balanced, full of dimples on the sides. Sort of makes sense it to be a timing mark, where is it ? Around 3/4" is 10 degrees...very roughly.

I have the black and white racing fuel gauge. The in dash gauge was replaced with a SUN Tac (vintage now) Might also have the oil pressure. Always wondered about the bigger size--never see them.

Jumping in and out of here.....loosen those rockers first, again, relax.
52  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: September 01, 2014, 06:49:02 PM
relax Smiley

take your plugs out ,rotate the crank CW, about a quarter turn until the indexing mark (dot) on crank gear is at 12:00   see John's illustration. your real close per your pic.

loosen your rocker arms so as no contact with pushrods---maintain order if you take them off. at this time all valves are closed, and will stay that way.

use your old gear and rotate cam CW till timing mark at  6:00, see Johns illustration.       stop.   read up some and wait for your parts.

I'm at the station today, will take a look at my balancer tomorrow and see where the dimple is in relation to the degree markings.
Reference marks crank/timing remember : 12:00/6:00
                                                             12:00/12:00
                                                              install dist.       
Just as posted above via John Z.

When all is done, read up on cold setting the timing....very easy to do. Think it graces this site somewhere. You are going to notice 100% improvement in your performance with the new chain and gear.

Also check for a loaner balancer installer....no reason it shouldn't press on smooth for you.



Just to brain check you : at 12:00 and  6:00  crank/cam, #6 TDC. rotor should point to #6 terminal on cap....dist could be installed this way.  If  you pointed it to # 1 terminal  withoutrotating the crank 360 degrees , 180 degrees on the cam ,which puts both  marks at 12:00....you would have installed it "180 out" a frequently used term, but less frequently explained.

Study the above picture per John, making sense Smiley    2:1   crank/cam ratio

pull the plugs ,will rotate very easy.

" some " of the well known ones

Gotta agree with Gary, crank gear looks good....and most likely superior to the well known ones out there, which have long since been outsourced. Quite a bit of writings on this a few years ago by engine builders.

As far as I know Cloyes maintains a good rep,as well as Lunati. We run a PBM , more than you need for your application.

About that #@#! TDC thing, pretty important thing to have a handle on when you start tearing into these. Yes, can put it back together exactly the way it came apart, as long as it's exactly the way it came apart.

Pick up David Vizard's book on " Rebuilding your SBC"  take a read through before you proceed, just a suggestion. Great reference material, jot a few notes in it on your engine. Jot a few notes from John Z's articles in it and some some of the info out of these posts pertaining to 302's fine tuning in it.

They make a distinct, beautiful sound when they are tuned correctly and screaming, but are not  forgiving being a performance engine if poorly maintained.

DON'T PULL THAT CAM OUT !

well....there's your wandering timing....

New gears will come in your timing set...go with a quality roller. I had a 68 Pontiac with nylon? timing gear, to decrease noise, but they were garbage. Was not aware they used them in Z's Huh Get that engine at TDC ,check alignment "dots" on your gear set.

Use blue locktite on your pulley bolts during reassembly. Crank snout looks good, make sure no play between your new key and the keyway in your balancer. IMO,if there is shelve it for a new one, but doesn't really look bad from the pics

Danny, Here in Ohio, we have a few car part stores (chain stores) that will 'loan' you tools like a balancer puller. You put down a deposit and get it back when tool is returned. Now, It might be hard to find someone at those stores that knows what a balancer or anything else on a car is that does not involve a laptop or a chip...but that is a different story.

I've been lucky, went through a bad spell a few years, stores got smart and hired in mostly retirees around here....guys who actually know what your talking about!
Summit is almost just as bad nowadays, keystrokes. The old Summit store and Supershops is were you talked over a counter concerning HP parts.

man,you 2 were quick!

Autozones, Advance Auto, etc.. out here have free loaners for tools. Say you need a new timing cover seal, which you  should replace if doing what you are doing ,they'll loan the tool out...they are in business to sell parts. No specific key per say, proper size is what you need. Take your old one in to match up .


Sounds like life's treating you pretty good out there, good for you.


Also....threads are looking a little ruff ( crank pulley bolt holes) I'd chase them to clean them up some.
