Ok, so I had a chance to get under the hood last evening. I discovered I had already marked the dampner at 36 degrees in preparation for this very test and then spaced it completely. At 10 degrees initial total timing was 34 degrees and just under 2500 rpm. I adjusted the initial up to 12 degrees and the total came up to 36 degrees at just under 2500 rpm. With the vacuum advance re-connected the total went up to 40 degrees at about 3200 rpm. I'll test drive in the next few days and report back.

Thank!

Snap! I should have thought about this. I have timing tape I temporarily installed to locate 90,180,270 in order to adjust the lifter clearances when I first got the car. I can re-install the tape to locate 36 degrees and then remove the tape. Probably be the weekend before I can mess with it again and I'll report the results back!

I'll check and see if the one I have does that.

Thanks,

Thanks for the replies! So truth be told even though I don't know what the all in timing number is since I didn't have a timing tape on the dampner I do know the total is up approx. two+ times the timing tab height. I believe the engine is getting plenty of timing. If I understand the replies (and yes I've read John Z's letter) it comes down to the curve of the timing as related to when the timing comes in?...

Thanks,

Hank

Hi you all, I'm trying to understand engine timing as related to the 1969 Z28. I realize the factory changed for that year and put the vacuum advance source to ported where there was no advance once the canaster was reconnected following timing adjustment. My history comes from once initial timing was adjusted the vacuum advance was reconnected giving you an instant bump in the timing setting. We messed with the initial adjustment a lot to find the correct amount for the engine configuration as related to performance.
So in 1969 they removed the vacuum source at idle apparently for emission purposes. I've read the articles indicating revamping the vacuum source to the distributor to basically reconfigure the system to prior years. Jump to real time today and I'm running approx. 10 degrees initial and once the vacuum is re-connected there is no real change in timing until the throttle is advanced. I don't have a total timing number but will say the car is impressive with no indications of laying over with higher rpm's. I guess the actual question here what does it matter where the timing comes from as long as the engine gets what it needs?

Thanks as always!

Makes sense to me.

Thanks for the info! The original is still out of the car and needs more repair than the local shop here can perform.

Best regards,

As best I can tell the car is still mostly original, but I don't have any prior maintenance info/log. I would like to keep it as close as I can within reason of course. I'm heading to the radiator shop here on Monday for a face to face rather than the previous contact which was by phone. Given the shipping fiasco happening these days I'd rather stay local if at all possible. I have seen the Glen-Ray name in prior posts; do they have a standard turn time?

Thanks,

Hank

I'll research the repair option further. Perhaps the shop was confused about repair pricing versus replacement cost.

Thanks you all!

Thanks for the replies! I've never been a big fan of additives so your opinions pretty much align with mine. New radiator it is then!

Maintenance / Coolant system Sealants

« on: January 20, 2022, 12:29:26 PM »

Hello to all!
Has anyone had experience using sealant tabs in cooling systems? The radiator in the Z is leaking and there is only one radiator shop here in town and their best guess to repair (if possible) is about the same as replacing with a new unit from Camaro Cantral. While it would be nice to have the original stay in the car I'm not sure I want to give the shop that kind of money for a maybe good radiator. I have heard of these different sealants with mostly positive reviews and would like to know what you all think.

best regards,

Hank

So if we are going off the original topic of celebrities I would submit the person I grew up with. He wasn’t a collector or accomplished road racer. He was just a guy who appreciated fast cars. When I was about 11-12 yrs old he had a 1963 Chevy 2 door Impala with a 283 4 barrel 4 speed car. In those days there were still real live gas stations. He was an attendant at a Phillips 66 station on Wadsworth Blvd. just before you would take the ramp to get on I-70. (This was in  Arvada Colo back in the day). During the summer nights I would sit on the front porch waiting for the familiar sound of a small block chevy with a wide open 4 barrel carburetor with otherwise complete silence on Carr hill. I’m sure I don’t need to explain further except to say he is the reason I became a chevy person particularly small blocks. My first car in high school was a 1968 327 4 speed Camaro. I learned from him how to make chevies go fast albeit in straight line fashion. He had broader views of cars than I did back then and succeeded in having a compliment of GTO’S and big block Camaro’s. I lost touch with him many years ago and hope he is still enjoying his fast car passion although he was 16-17 yrs old back then and I’m now 66. I’ve had the great fortune to re-acquaint myself with my dream car and now own a 1969 Z28 Camaro. Small block meca for me thanks to him!

In this instance the car is a standard interior. Was the decision to install blankets driven by solid lifter noise?
Thanks,
