Originality / Re: Z sticker on glove box
« on: October 04, 2018, 11:58:21 PM »
I have a NOS hood latch that had surface rust all over plus the sticker still on it.  I soaked it overnight in Evaporust, then dunked it in water several times and lastly sprayed it with Gibbs oil to keep it from re-rusting.  It looks pretty much like brand new and did not affect the sticker.

Interesting information and thank you for sharing.  I had just assumed the dogleg reference had something to do with the little kickout in the lower right part of the port floor as seen in View A above.

Trans-Am Camaros / Re: Crossram manifold

I don't think you're ever going to find a "hard" date for when the 4295 replaced the 4210 carb but it would have been sometime during the summer months of '68.

I don't have a collection of photos showing 4210 and 4295 choke tower numbers so I personally can't help with that but maybe someone else here can. Some of the pictures above show numbers altered with an electric engraver. I would not call that etched, and there is no telling who altered those numbers. Maybe I'm wrong but that does not seem like something Holley would have done.

You are correct that there is an error with the '68 cross ram carb listing for '68 on our carburetor page and I will get that fixed when an opportunity presents itself. The 3810 is thought to have been a developmental carburetor while the manifold was undergoing initial development.  There would not have been a cross ram unit that left GM for public consumption with a pair of these 3810 carbs on it, in my opinion.

The '68 cross ram carbs should read...
302/290 (2X4) 3941140 (early) Holley # 4210
302/290 (2X4) 3957859 (later) Holley # 4295

You're also right about the 3942595 part number being incorrectly types for the carburetor when it was one of the fuel pipes so that is another thing for me to fix. I appreciate your help so that I can put correct information out there.

I don't believe the 4295 is the first Holley double pumper as I remember talking with GM engineer Bill Howell (part of Vince Piggins' Product Promotion Group) and he told me years ago that he was testing an 800 double pumper carb on the Penske Camaro right after the '67 Trans-Am season finished. This was before the cross ram was available and was in the Oct-Nov 1967 timeframe.  I just asked him again a couple of days ago about cross ram carburetors and double pumpers and here is his reply..."As a test engineer in the lab, I had no release responsibilities, so I did not keep track of part numbers and minor differences in many new parts being considered for release.  By the time the 2x4 package was released for production, I was in Vince's group, so I had limited interest in those details.  I knew the carbs were 600 cfm, and their double pumper characteristics.  In their production layout, they were difficult to work with, so we reversed end for end the float bowls to get the fuel fittings outboard.  This also increased the difficulty in setting the fuel levels, as in production, they were different front to rear. I would have to adjust the fuel to the bottom of the sight plug, and then raise or lower it to the correct recommended level after reinstalling the sight plugs.  Your recollection that the Marlboro test in 1967 probably involved a double pumper 800 cfm is correct in my memory (tho I have no written record for reference).  It amazes me how accurate my memory of the 1960's is compared to the 1980's.  I guess that speaks to the level of excitement I was experiencing during those times.  I hope the above information is of benefit for your research."

15x7 trim rings won't fit on DF wheels.

I think it was the other way around. The 4 was too close to the 1.

Tony, are the original quarters and fenders no longer there?  If they're still there, I would use them as your guide for where to drill.

Craig and I were friends. He was an underrated racer and a quality human being. He earned the first points for Chevrolet in the Trans-Am by virtue of his second place finish at Daytona and the first points for Pontiac when he raced a Firebird in '68. He will certainly be missed.

Trans-Am Camaros / Re: Unusual valve covers and intake ??
« on: August 05, 2018, 12:10:49 AM »
It looks like an Edelbrock SY1 Smokey Ram intake manifold that has had the lettering ground off the lid prior to polishing it.  I have never seen Moroso valve covers in that style before.  Kind of an interesting look.

No documentation as being a real Z-28 but may have real Trans-Am history.

Was in the well known multi-car crash at Road America in 2005.

I got myself a dated Holley carb too.  Thanks for the heads up.

Great to have you back, Mike.  I understand your issues with Photobucket.  I paid the $400 just to keep the pics alive here but I'm very relieved that they got wise to that lunacy and made the cost more manageable.

Yes, it is a nice car.  Of note, it originally had the U57 tape player on the front of the console. When restored, the owner at that time preferred adding tach and gauges. It was not a gauge car when new. A 6K redline tach was evidently installed but that is not typical for an LOS car built May and later, which this car is.
