Does anyone know what speed they were running on the Daytona caution laps at that time??

PS:  From the reported data I could find, in that race they experienced 11 cautions for a total of 60 laps (150 miles of the 500 mile race).  The Average speed of the winner (Cale Yarbrough) was 143.251 mph for the 500 miles.   The total race time was 3.5 hrs.   If I estimate the avg speed during 'hot laps' at 185 mph (based on the 189+ mph qualifying speed) then the hot laps took ~ 1.9 hrs of the race (at speed), leaving ~1.6 hrs of the race being ran under caution.   With 150 miles of the race being ran under caution (in 1.6 hrs), the avg speed during the 'caution laps' was slightly over 90 mph!   So Basically during this race, there were 11 periods of ~ 5.5 laps each (12-13 miles) ran at speeds over 90 mph (For the pace cars as well)!

I'd guess taking even a prepped stock '68 Camaro and running it for 12-13 miles at over 90 mph WOULD cause some heating problems (certainly given no opportunity to cruise at 60 for the engine coolant to cool).. so it doesn't surprise me at all that the pace cars suffered from overheating!  :)

:) .. so how about a short synopsis of your presentation for those of us who couldn't be there??  :)

Read the links...   but based on the information you presented, it is *possible* that the block was a warranty replacement (short block) for a '71 LT1 engine (but apparently it's missing the internals if all you have is the block?)..   No way to prove it, especially without the internals...

While I'm not a big block fan, if one is going to have one....  aluminum heads address a couple of the problems with them..  :)

PS.  I walk right by big block anything....  so maybe I've been within *sight* of one or more, but didn't *SEE* it..  :)

The L89 option was not a 427 option, but instead was an option for 'aluminum heads', which work fine on 396 (L78 engines) and while I've never seen one myself, I understand there are original '69 Camaros carrying those from the factory on 396 engines!

Originality / Re: Rosette shape variances in 67

Looking closely at the VIN plate on the car being discussed (the yellow car), it seems that while the rivet is not the typical rosette shape, it is also clear that the rivet is NOT a standard round rivet.. one can see very small extensions where the rosette would be...

It is not known how availability of COPOs 9560, 9561 & 9737 was communicated throughout the dealer network. Legend has it they were supposed to be exclusive to their respective dealerships, Gibb Chevrolet and Yenko Chevrolet. But Berger Chevrolet learned of them early on and initially ordered one of each. Their ZL1 [body # 211785] was actually ordered prior to Gibbs' 50 car order.

I've seen several 1969 dealer ads announcing the availability of 427 Camaros.   Guess the secret got out at some point.

Except for the COPOS, the *factory* did NOT install 427's in Camaros.   Dealerships DID swap engines and install 'non-factory' engines for high performance customers.. such as Baldwin Motion which was well known and displayed in many high perf magazines of the day!

I saw a 69 unrestored car at the "survivor show" in Bloomington a few years ago claiming to be a rare L88 SS Camaro. Are you saying this was not an available special option, and he could have only gotten those over the counter for a 69 Camaro?

No factory L88 Camaros from 1967 to 1969. Period.

I do know a few things....

Bryon,  I believe your statement would be accurate leaving off the '67-69 limitation!   :)

unless you know WHO Rebuilt an engine, just saying *rebuilt* doesn't carry much weight (not with me anyway - I've taken apart 'rebuilt engine' with the rods in backwards, and many other problems), obviously 'built' by people doing their 'first one' who didn't know what they were doing!   To fire up an engine like that without disassembly and proper reassembly is putting all the parts therein AT RISK...

your photo looks consistent with the AIM (at least as how I view it)....?

Run an amperage test on the battery. I've seen dead or bridged cells give you enough voltage to run the lights, but no "oomph" to start the vehicle. Try replacing the battery with a spare if you don't have an amperage (load) tester.

Rolling it a few feet forward would not 'fix' a battery problem, whereas it *might* get him a better ground...?

Sounds like a poor 'ground' problem to me...

In reality, there are only two rear shock types available for the Camaro. With single leaf or with multi leaf. You can go economy like Monroe, or performance like KYB, but it all depends on how stiff you want the ride to be. Go to Rock Auto and browse around to see what's offered.
Ed

For original restored, the best (and only truly accurate) would be finding original shocks, but Ed mentioned Monroe which aren't original and don't even appear to be a simulation of original (Monroes are fine for a non-performance car) but I don't think the Monroe 500 is still being made is it? 

KYB are not original either, and I've heard of many failures with them. 

For performance (handling/braking/etc) Konis have generally been no.1 for a long time, but maybe I'm out of touch?  I'm surprised none of the fellas with Z28 s especially aren't running them.   On my car currently are Gabriel Striders (purchased long ago) - painted gray to appear like original at least in color,  but I have new Konis to replace them at some point...

Don't any of you run Konis on your Camaro??
