Trans-Am Camaros / Re: Single 4 barrel on a Cross Ram intake?

« on: December 23, 2021, 07:47:48 PM »

The Smokey Ram while being similar to a cross ram, does take somewhat different parameters to tune properly. I wouldn't feel comfortable taking settings off one to use on the other.
  I do have the Smokey Ram on my 68 Z/28 A/S with the 830 Holley and it is tuned quite well. Of note, the history of this car goes back to many consultations with Smokey himself to get the tune right.
   This installation is on a relatively stock factory 302.

Anyone have say a 1971 or so Holley Catalog ?[/size]  To look up the 4210 & 4295 Specs
in the Numerical Listing, mainly orig Squirter Size(s), Jets, Power Valves, Venturi & Throttle Dims...
Pretty sure both have all (4) 1-9/16" Throttle Dia 1-1/4" Dia Pri Venturi and 1-5/16" Dia Sec Venturi.

1988 is the oldest Holley Catalog I have and both 4210 & 4295 are absent from the Numerical Listing in the back...

This is from the 1975 Holley Catalog:

Mild Modifications / Re: 73 M21 in 69 SS396 (Custom Shifter Mount)

« on: October 10, 2015, 03:13:14 AM »

I'm trying to make up a mount to mount my stock shifter to my 73 M21.
 I'm going to try to make a mount out of a solid block of aluminum that I have.

I think you are on the right path and should be able to come up with an acceptable mount. I'll post some photos of a couple I did to give you some ideas.
The first three photos are of an original M21 in a 68Z, SCCA A/S road racer. This is a race application with straight shift rods and no console, but does show what you can do with the mount.[/URL[URL=http://s1223.photobucket.com/user/1969Muscle/media/DSCF4265_zpsbt4tw5yo.jpg.html][/URL[URL=http://s1223.photobucket.com/user/1969Muscle/media/DSCF4281_zpsloenzrxt.jpg.html]

This is a photo of another project with the larger output shaft. It has a slightly different offset, but the same basic idea.

Keep in mind you will need to have a relief in your mount for the main pin that protrudes out of the shifter when in reverse, that is the larger hole in the mount plate. Your solid aluminum piece should work, but the use of a thinner mount plate and spacers allows for some offset adjustment as needed.
Hope this helps!

General Discussion / Re: Another LS7 lives again.

« on: June 16, 2015, 05:18:43 PM »

It's great to see another LS7 coming back to life. Darrell, those valve spring dampers were always a problem with breakage.

I have a LS7 454 crate engine I bought new back in the early 70's. It has been stored in my shop for the last 35+ years. I recently opened it up and gave it a freshening. The engine is still standard bore, 100% as Chevrolet built it. Back in the day I street raced it. It did well.

 I have decided its time to relive my youth somewhat and get this thing back on the road, but this time racing it only on the track and driving it a bit more conservative when on the street. It will even see some road race time.  I'll be putting it in a road race modified '69 C10 Stepside with 4.1 gears with a Midwest Muncie M23 4 speed. I wonder if the LS7 will be anything as fast as my memory recalls! and the sound of that cam!!

I hope you enjoy yours as much as I anticipate enjoying mine!

Jerry, are these the type you are referring to?

Hopefully I've successfully posted images of the front and back of the TA70 six spokes AR wheels below...

Trans-Am Camaros / Re: Fire Extinguishers

« on: August 04, 2014, 12:27:18 AM »

Hi Tom,
    I have three mounting brackets here in front of me. One aluminum and two in plastic.
The aluminum bracket has a four bolt rectangular pattern mount. The holes are spaced at 0.09375" x 4.875" center to center.

The first plastic mounting bracket has three holes, all in line.  They are spaced 1 11/16" and 3 3/16" apart. This piece appears to be older and shows signs of shrinkage. I think the dimensions may have been maybe another 1/16" apart when new.

The last plastic bracket has only a two bolt pattern, with the holes  3 1/4" center to center.

Let me know if any of these match what you need and I can bring it up to Monterey.
Robert

Hello Tom, and welcome to the Forum!
     
   I believe I have an Extinguisher that looks very similar to the one in Jon's photo.  Unfortunately I won't be able to get to it till later this weekend, but I will check it out.

It's nice to see another seat variety. Considering all the different manufacturers back in the day, there just are not many left.

Is the Putnam Trans-Am Camaro currently track worthy, or under restoration? Either way I hope Dave Doyle is able to utilize the seat.
Many thanks for sharing.

Trans-Am Camaros / Fire Extinguishers

« on: July 27, 2014, 01:09:07 AM »

There are a lot of options out there for an "in car" fire extinguisher. It would be nice to see what some of the cars are currently using and what was used back in the day.

The State's 68 A/S Camaro was equipped with the standard hand held fire extinguisher.



An interesting inspection sticker attached, dated 1973, by the San Francisco Region, SCCA.



Wanting an exceptional fire system in the car, I installed a Halon system. Not vintage, but I feel some exceptions are necessary when it comes to safety. The system has nozzles plumbed to the fuel cell area, under the hood, and of course the passenger compartment. The system is easily activated by hitting the big red button next to the driver.

Jon, That's great that you found one of the "Total Comfort" seats. They are tough to find in good condition.
Did you find it with the cover, or are you going to have to have one made?

The rear of the Leslie "Total Environment" racing seat has their manufacturer's label attached:



The seat back is smooth with a nice finished feel to it. The back itself is reinforced and anchored to the roll cage.



The base of the seat is molded to fit snugly around and bolted to round tubing, or in this case solid round stock.



The steel base frame bolts to the original factory seat attachment points. The frame has two adjustment positions. The back support also has two corresponding positions.



When assembled, the seat is sandwiched between the solid round bar of the base frame and metal reinforcements. The quilted Naugahyde covers and cushions all of the hardware.

I don't know if the seat designed by Solar Plastics was called the "Total Environment Plus" seat
or not but comparing these two ads, it seems like it may have been. Anybody know for sure?

The seat as found in the former State's A/S Camaro appears to be the Leslie "Total Environment" model. No track time on it yet, but I can say it is very comfortable sitting in the shop! Seems to be a very well built unit.

That's a cool find Jon.
Will that cap be used on the Johnny Moore Camaro?
