There are many restored cars out there with U17 and no clock. That's an indication that U17 was added or the dash housing was replaced.

Restoration / Re: Cowl induction air cleaner base tube
« on: March 30, 2020, 07:49:42 PM »
It's part of the base, crimped or tack welded in place. Not the same as the rocker cover tube which is 3/4". Early production tubes were 90 which will not clear a double-pumper carb. 2nd design had 2 45 bends.

Some of the older service replacement open element air cleaners included a bag of different vent tubes to cover a range of applications.

Best charger I have ever had. Hook it up in September. Keeps the battery at 13.9v until May. Unhook it and go. 9 years old, still works great.

Hydraulic lifter engines.

Chevelle, Camaro, Nova BB covers were chromed.

I wonder if the defogger was added. If so, someone chased down a rare part - the top/defogger dash bezel.

It's reproduced.

From the ad:

"ALL OF THE NUMBERS ON ENGINE BLOCK,TRIM TAG,AND VIN NUMBERS AND THE ORIGINAL PROTECTOR PLATE WILL VERIFY MY STATEMENT"

Nope. POP is from a different car, 124379L503860.

1969 Chevrolet Camaro RS/SS Pro Touring

That's a 6-cylinder VIN. Could have been an RS. Nice resto-mod build so doesn't matter much.

They did use different stampers, probably done at different points during final assembly.

It is not unusual for Norwood engine/trans VIN stampings to differ.

Last year as a production option was 1977-my Malibu had them. GM and Kelsey serviced them well into the '80s; we were buying 14 x 7 and 15 x 8 rally wheels by the pallet load. No one knew or cared about codes at that time.

So I a not an engineer. what is the ideal down force? And how did the other cars of the era on the test perform?
thanks

Not sure there is one. Would have been interesting if they could have also measured the aerodynamic drag each spoiler added. That's the trade-off. Adding wings, etc. adds aerodynamic drag, slows car down. Front lift is complex to manage. It is produced not only by air flow under the car, but by the front tires revolving at high speed. Penske/Donohue cut a ducting system into the cowl, doors, quarter panels on their T/A Camaros trying to vent the engine bay but the SCCA made them remove it.

Get it right and at some speed, total aero downforce exceeds the weight of the vehicle. Theoretically, it could be driven upside down...
