I have always kinda hated those rounded-triangle mesh air cleaners that kinda look like urinal cakes. (Apparently they're Edelbrock "Pro Flo 1000". *snort*) But I'm thinking of using them on a full-fendered '34 Ford project with cragars, aiming for late 60s (or even 70s, at which point I won't be able to post it here!)
I think I remember seeing those in Rod Action, somewhere around '73 - 75'ish timeframe, as well as the last of Rod & Custom magazine which died out the first time around '74. So they are out of the parameters of TRAK's cut-off. Didn't the ugly Corvette in Corvette Summer have that air cleaner too?
In the '80's my '67 425 HP (Convertible Hardtop) 'Vette had 3 of them on the triple Rottenchester two-barrels, they were so ugly and loud, that I replaced them with a stock Chevrolet Corvette air cleaner. All three of them are probably somewhere in my Dad's garage, if he didn't toss them too! I think his '70's Mercury Merc-Cruiser boat motor had one of them on it's 2 barrel carb, it got crusty and rusty and replaced with a Cal Custom flat pan air cleaner.
