Just curious:  what was the brand of the 'new one that did NOT work'??
shows to go ya..   sometimes the new stuff is bad too....
1937  Camaro Research Group Discussion / Originality / Re: 69 Z28 Radiator Re-coring ? on: April 04, 2013, 11:27:37 PM
Yeah, a better word for the 'radiator' would be 'convector', since the cooling is predominatly by convection, rather than radiation.  (Actualy there is conduction/convection heat transfer from the hot fluid to the tube/fins, and then convection/radiation from the fins to the air moving thru the fins)..
For radiation cooling, being flat black would be good, but for convection, I'm not sure 'color' makes a difference... so only issue is if the fins (Cu and Al) need any anti corrosive coating?  but I'm concerned about how the Harrison radiator factory did it..  as I want to match their process as closely as possible...

Thanks TModel.. Smiley ..  that's good advice...  and very correct re 'too much paint'.
I am curious whether the fins need any paint at all, of if I should leave them bare..?

OK, I FINALLY have my radiator back, after a long process of finding the radiator shop in Nashville that would reuse my original core rails, then looking for a more local source to do that same thing.  I finally got information from a core manufacturer, that they would *use* my original rails with some restrictions and requirements, but they would have to go thru a commercial radiator shop.  I then found a more local shop (12 miles away) that would work with me; ie. disassemble the radiator, give me back the parts for cleaning, and then order a '69 Camaro core' (from the supplier I identified) - notating that I would send them my original rails, bead blasted and cleaned.   This all took a few weeks to get the radiator shop an account set up with the core manufacturer, and 2 weeks ago I shipped the rails to Dallas; they installed them on a new core and provided back to the radiator shop on Monday of this week.   Yesterday I picked up my original radiator (UH), re-cored with a new core using my original rails.  See pictures attached to this message.   I asked them not to paint the radiator, as I wanted to do it myself!  Smiley     NOW, I need some recommendations from you guys that have restored radiators before to suggest the best means to prep and paint the radiator!   All suggestions appreciated.  My goal is to duplicate how the factory did this as closely as possible!    I intend to clean with lacquer thinner, and prime?  is a special primer required for the combo brass/aluminum parts?  and then paint with a glossy black to match the factory.  Should be finned part of the radiator be primed and painted also?
ALL suggestions appreciated!~

If the water isn't flowing, and the thermostat isn't impeding the flow, then si there anything else that might be impeding flow?  or... Perhaps your water pump isn't pumping....?

Mine also were of the type shown in your bottom photo (the old rusty one).. Smiley
1942  Camaro Research Group Discussion / General Discussion / Re: Charlotte Autofair on: April 01, 2013, 10:43:50 PM
What is the date again?
1943  Camaro Research Group Discussion / General Discussion / Re: It's Baack-----2014 Z28 on: April 01, 2013, 10:37:00 PM
Are you saying that you got used to the 'sitting in a hole', and the poor visibility  from the drivers seat after driving it two days?
1944  Camaro Research Group Discussion / Restoration / Re: Subframe Crisis on: April 01, 2013, 10:34:27 PM
Thanks Steve,

I had always suspected that my front clip had been repainted due to those two things:  1) slight difference from the paint from firewall back, and 2) thin coverage on the inner fender area...   Now I'm not sure....  Smiley

Thanks ZLP.. Smiley    for correcting my post.    Shows how little attention I paid to the 'yellow'..  *L*..    usually I didn't pay a lot of attention to the 'factory redline' either since I removed the original tach and installed a Sun Super Tach in the dash and had the redline set at 7000 after I rebuilt my engine (in the 70's).   Pictured below is the original tach from my 09C Z28, and it does 'yellow' at 5700 (not 5500) and reds at 6 grand.  I had it rebuilt 30 yrs ago, but haven't operated it since.   I'm planning on reinstalling it and HOPE it works better now than it did before.

That sounds good..  Smiley    I thought you'd only purchased the dated mirror glass, and was going to install it yourself in your original housing...
1947  Camaro Research Group Discussion / General Discussion / Re: It's Baack-----2014 Z28 on: March 29, 2013, 12:16:21 PM
I've driven a 2007 Corvette Z06 with the LS7 (427 ci engine).  That engine is amazing..  not only in the power level, but also how quickly it revs for a big cube engine (not at all similar to the 'old school' 427 engine!  My main issue with the 'new camaro' is the body .. size, weight and visibility from the driver seat.  I think they tried to do too much in that desgin, and tried to capture not only the 1st design shape, but also the 'cartoon CARS' or whatever.. brutish look, and in doing that it loses a lot of the 'retro appeal' (at least for me).

That said, I like a lot about what GM has seemingly done for the Z28 model, and the PM's enthusiasm for the car, but I'm very curious what the price point is gonna be.. Smiley.   In the past, when proposing that the Corvette offer a 'stripped down' model (wtih options), we were told that it was more expensive to offer the options (which complicate the assembly process), than to just put all the options on all the cars (ie. AC, PW, PS, etc)..
1948  Camaro Research Group Discussion / Restoration / Re: Subframe Crisis on: March 29, 2013, 12:09:29 PM
Thanks John!   That's new information to me, and beneficial knowing that.  I assume your explanation referred to the Norwood Fisher body plant?   
What about the paint on the front fenders, hood, valence, and other parts painted in the Norwood assembly plant??   
Were those parts painted with an automated system? or manually painted?  I'm curious because the 'inner' portions of my front fenders (the part inside the engine compartment) didn't seem to get full coverage; as if the painter sprayed from above and the under areas where there were contours, didn't get much paint...  Is that typical of factory painted fenders on a '69 Camaro?   
Maybe Steve S. has some information on that as well from his survivor/original judging activity?
1949  Camaro Research Group Discussion / Decoding/Numbers / Re: Any info on door mirror dates. on: March 28, 2013, 09:42:36 PM
Did they provide info on how to remove the old mirror and attach the new one?
1950  Camaro Research Group Discussion / Maintenance / Re: What are these marks on the harmonic balancer? on: March 28, 2013, 08:51:43 PM
When the timing mark on the damper is at the 'TDC' mark on the pointer, the piston is always UP at TOP DEAD CENTER, .. BUT.. 
1) the piston might be UP on Compression (which is the one that counts for timing), OR
2) it might be up on Exhaust (in which case the exhaust port will be open). 

Just pull the LH valve cover and observe the rockers as you rotate the engine thru the 4 'strokes'  (intake, compression, power, and  exhaust).  If you've never done that before, it will give you a new appreciation for the engine operation.. Smiley ..  and don't forget that the crankshaft is rotating twice per rotation of the cam, and that makes ONE cycle of the engine.
