Restoration / Re: 4053 Carb Ink Stamp Font?
« on: April 10, 2021, 03:47:30 AM »
Found a photo.  This is the correct 30cc accelerator pump for the GM Holley production carbs.  Even in NHRA's Stock Eliminator class where I compete we are not allowed to install the larger 50cc pump.

I'll post a photo tomorrow but yes all of the original carbs have the countersunk holes with clutch headed screws.  Here's a bowl photo from the survivor '69 Z28 I owned about 12 years ago, 27,000 mile car.

All of the original Holley's made for Chevrolet do have the ink stamping.  Here's another virgin from my secret stash of parts, dated 854.  I can also barely see part of the 4053 ink stamp on my 25,000 mile survivor Z28.  Some carb restorers are ink stamping carbs but the fonts are not even close to correct.

Gardner Exhaust has the most technically correct exhaust for these cars and it's the only system allowed for concours judging.

I'm sure that many or most of those L78 convertibles were bought my NHRA sportsman racers.  That engine combo in a convertible changed the class and bumped you down the ladder a bit over the coupes.  Case in point, Ray Allen and the LS6 convertible.  That car was undefeated at all NHRA national events in 1970 and won the NHRA world championship.  Yet the stick shift LS6 cars did not set the world on fire in Stock of Super Stock eliminator.

This Z28 just hammered at $127k plus the 10%.  Not bad for a much smaller auction house.

The black Z28 going to Greensboro is a nice car.  Not concourse perfect but does have nice paint and original engine and rear axle.  Black with red interior is very, very rare.  This car should break the bank.  Last fall, a driver LS6 with everything wrong including replacement trans and rear axle went for $135k there. 

Many clients are telling me that investors and collectors are back in full force with collectable commodities with the new administration in the white house.

The Greensboro auction has been picking up steam too.     

Get out the popcorn,

Most real black Z28s go for big bucks with original drive trains.  A known survivor I certified went for $175+ a couple of years ago.  I've seen a bidder spend $100k for a Z28 at BJ when it was announced that the car had a non OEM trim tag!!!  Black sells.  People do crazy things for black cars even if it wasn't a real black car.  Personally I hate black, always did.   

It's troubling that the makers of these tags are getting better and better at it.

I finally had time to do the analysis on Burton's '69 Z28 and told him to post my analysis report here on this thread.  The trim tag is one of the newer reproductions and yes they are getting better at making these non-OEM tags.  Older repros are very easy to spot, this one a little harder.  Have seen many repro tags over the past 9 years  working at Barrett Jackson.  However, the complete drive train to this car is real and authentic to this vehicle.  This is the original drive train that was installed in this car when it was built.  I have dozens of the 407 date along with Muncie stampings.  All characters are spot on.  It's a very honest car except for the trim tag.  And where Burton has the car priced at $75k, that's not a bad deal.

Two hole gaskets were factory installed so cutting off the extended gasket hole is the correct way to go.

Restoration / Re: Cowl induction air cleaner base tube
« on: March 30, 2020, 08:49:46 PM »
Only thing you can do is find an original open element base and rob the arrester tube off of that.  It's basically the same and can be tack welded in place.  Length may be slightly different.

Those are the bleeder screws and they are set by Holley when the carbs are built.  You should never have to go in there.  I don't have to fool with these on my Stock Eliminator '67 Z28 race car either.  If someone monkeyed with them, they may have to set and recalibrated.  Have you checked everything else out on the carb?  Warpage, correct jetting, dirt in the carb, etc.

A potential buyer just contacted me about this car this morning.  I have almost 230 cars in the registry now, this car is not in the registry. Not the best photo of the trim tag but I will say that it does have issues.  The L's are also not correct.
