No work on the car today. Plan change... I am on with my Father Friday night to Monday morning. Bummer, was really looking forward to getting some work completed and maybe even go for a ride. But 84 year old Pop's has Dementia and Alzheimer's and can't be left alone. 30 weekends a year GONE! I know it's the right thing to do. It wouldn't be so hard to do, if he would at least remember beating the living hell out of me growing up. But Mom died of Liver Cancer in '04, and he thinks he never touched us kids. It was the thing to do back then I guess. But I digress... Danny

I wonder why it doesn't roll that well? Danny

What's with the two different 3's in the VIN? The one on the right looks like it was done with a handheld engraver. Sure looks pretty beat up overall for only 19K miles. I would have to see it right in front of me, AND with the POP in my hand.. Danny

Someone MAY want a challenging long term project... That's rich!... Too funny. D

Can't get the pic's much better. Never seen a baby "MO" stamp like that, and all crooked??? Guess I am about to learn something... Danny

So I was told there is no 5.0 Power Valves. Only 2.5, 3.5, 4.5 and 6.5... Is it ok to run the 4.5's with 10 inches of vacuum? Danny
262  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: September 17, 2014, 08:51:15 PM
Ok, parts ordered. Will try to get it all back together on Sunday and see what happens.
 Compression is 155#'s to 175#'s. With # 8 at 180.... Danny

Decided to take a look in the carb. I have to know what's in there anyway for proper set-up and diagnosis.
 
 Pump shooter is 25... Primary jets are 68.... PV's are 6.5... What do I order Huh ... Here is the actual carb I got...

Ok, all sounds good. I didn't do the rotor skip trick, as it fell right in place both times, so maybe I got lucky. I thought that distributor sounded all set-up correctly. It must be the carb. Cause when I try to adjust the fuel/air in, the idle just keeps climbing up and up, and with the adjuster screws all the way in it idles up to 2,000, but doesn't die. So I couldn't get it correctly adjusted. I bought this carb new off line. I don't know what it has. My original is boxed for now, as I think it needs more throttle bushing work etc, it's binding and not closing all the way.. I will send it out to a pro rebuilder when I get the money. Maybe this winter.

 Why did it run better with that crappy distributor ?

  Vac at idle is 10. So I will pull this carb and install 4.5's or 5's ?? It probably has the 6.5's in it stock, but not sure. I will go check the Vac at static idle tonight, with the original Dist. installed. I wanna use that one to measure Vacuum again correctly, right ? ... Danny

Update... I realized that I was trying to line the rotor up with the # 1 Cylinder, Not on the rotor. I know, not real smart. I found TDC # 1. Dropped the dist. right in and it's pointing to number 1. Amazing how easy that was when ya do it. I installed the wires as described and she fired right up. I keep getting conflicting advice about the dwell setting. Some old timer told me 32 is too high, and go to 29. All the books say 28-32. So I set it at 29.5. Another guy who is the Bowtietuner told me 32 is too high, and go 29. He seems to really know his stuff. Good for now. Timing set, idle set, fuel/air set. Warmed it up and took it for a ride, and it won't pull. Picked up off the line well, but once I get going it starts to hesitate big time. Took it back to the garage, pulled the dist. and changed the rotor over to an old dist. from Kragen that I had laying around. I threw the rotor on and filed the points real quick, dropped it in and it fired right up. Set the dwell at 30 etc. etc. Wanted to see if there was a noticeable difference and there was. It was a MAJOR dog off the line, Had to ride the clutch, but once I got going it pulled like hell, and blasted right up to 80MPH. SO, the original reworked dist. is advancing, but coming in to early. So I need something in between right ?   I wish I could just change the springs and weights myself. Anybody know what I need to buy, do I need the weights also? I'll tell ya just pulling on the throttle from outside the car and it revs right up with no hesitation. But I know that old Kragen dist. is not performance oriented. So I need to rework the original dist. Here is what I found from the shop.

   Advance starts 11-1200 all in by 2,800 to 3,000. Has 18 degrees mechanical and 10 degrees Vacuum. That's all the info On the tag. And it reads 10 degrees vac on my test gauge. Should I have it come in later, at say 1,500 to 1,700? Or maybe 1,800 to 2,000? Note also, he changed the vacuum pod. It has a number on it that says B26. Anybody know what that is? He saved the original pod and put it in the box.

 Almost there guys, thanx for everything so far. Home stretch me in...  Grin Grin  ... Danny

I think the advance is coming in too early. I gotta drop in my stock dist.... If it revs up nice and seems to be ok, then I know I need to have the stock dist. reworked AGAIN. Maybe all in at 3,000, instead of 2,400.  Update soon... D

I put the wires ONE over CW and it won't even fire Sad   I shift them one hole to the right and it fires right back up. Meaning CCW one. I Have # 1 there because that is where the rotor points when it's a TDC.?? The picture you are showing has # 1 way over next to the vac pod. The rotor doesn't face there? Looks like my rotor at TDC faces where the # 7 is in the picture. Actually between the 2 and 7.. I feel ignorant for sure. I Guess I will go ahead and move them all over two and see what happens.

   Ok, I just put the wires like the picture and it doesn't even fire, more less run. WTF!!!D
268  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: September 14, 2014, 07:11:04 PM
I will go check... D
269  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: September 14, 2014, 07:02:10 PM
What I mean is the rotor is facing cylinder number 3 when I index it, not number one. I can't get it to face number 1. Now that I think of it, maybe I need to rotate back all the plug wires one step. I thought it was supposed to face the number one cylinder. But now I am thinking it needs to face the number position in the cap??... Danny

Update...Removed the resistor from the mix. Pulled the distributor at least 25 times and could not get it to line up with the rotor pointing at NUMBER ONE!. It always points to number 3. There is no tooth in between section. I tried 20 or 30 times in 3.5 hours. It would never drop facing number one, no matter what I did. I kept turning the pump drive slightly and trying to index it. But it eaither fell right back in the same spot, or it went to what I guess is the next tooth. Pulled the number one plug out and brought it to TDC, and did it again and again. It runs, and doesn't backfire thru the carb... "IF" you shove the vac advance pod all the way against the intake. And even then, you can tell it's just not right, as it has that sound of missing. I rotated the crank and watched the rotor turn. When the rotor is in the center of number one piston, the crank mark is at the last line on the bottom of the timing tang. 15 degress or so out. The thumb over the hole trick couldn't be done, as it was too hot. So we put the compression tester in and used it, and it worked fine.
Float bowl levels were good up front, bad at back bowl. Adjusted it, now ok. HELP!!! Dist just won't go back a tooth.
Also I was wondering if I used the correct mark on the crank gear. The new crank gear had 3 marks on it. I used the circle mark to line it up. Should have used a different mark??? Like the arrow mark, or other mark. Could that be the few degress off issue?
Vacuum is at 10

Geezo, ALL MY WORK!!
