'72 Expansion Tank?
My recently aquired '72 air roadster does not have an expansion tank and I do not see any evidence that there was one. Should there be one?
Thanks,
Roy

The tank on my '72 vert was shaped like a fuel tank and bolted to the rear of the driver's side inner fender liner...probably still there, easy to miss....mine was broken from metal fatigue and so I cut it outta there but was unable to fix it.....this was some 15 years ago....I tossed it, and used that space for a cruise control....
for years I ran the car without one, only need operate the lights/wiper doors with the engine running anyway....

Yes, my '72 BB with air has a brass tank painted black while I've seen the same car with no air have the aluminum tank.
Only base engine small block cars from '72 would have no tank. The LT-1 cars do have the aluminum tank.

My 72 was a SB now BB non air car. My question is , if it were original would it come without a expansion tank or with one of these? I'm guessing none because I have this and plan to use it to prevent puking. Of course everybody at a car show is an NCRS judge and will point that out.

Not true the LT1 cars did not have an expansion tank. The coolant overflow hose dumped right on the ground.

Base engine with AC and/or automatic transmission had no external expansion tank but relied on the copper radiator tank for thermal expansion of coolant.

Also , I was implying that car show attendees pic apart cars like they were judging for NCRS , that does imply that NCRS judges are a-holes. But thanks for changing the meaning. You harp about NCRS judges getting a bad rap and being called a-holes in other threads, what do you do?
Jeez...one bad apple ruins it for the rest.

Maybe I'm missing something but is this Mike Ward implying somebody ELSE is an A-hole?!?!? Imagine that. Practicing how to make/keep friends again Mike? Almost every thread you're involved with you seem to ruffle feathers.

-Your post contributed nothing to answering the OPs question.
-You tried to hijack it by asking about your own car
-You deliberately threw in another bash on NCRS and the NCRS people even though that's completely off topic.
-Your response above redoubled your attack, despite some seriously flawed logic.
And I'm the trouble maker?
BTW- your initial post confirms that you don't have a clue what the expansion tanks are for and why your intended use for it will fail. Good luck with your project.

As thin skinned as always I see. Don't go throwing stones if you're so sensitive.

Ok, going straight from the A.I.M. :
Base with manual trans = aluminum
Base with A/C or auto = none
LT1 with or without A/C= none
ZR1 = aluminum
LS5 w/o A/C = aluminum
LS5 with A/C = brass
Sorry about the confusion.
