Chad, the Mark Donohue Performance Products items are neat. Do you happen to have a catalog and know what sort of things were offered?

The dash in the car looks very similar in layout to the one seen below (from Pat Ryan's Penske Camaro). Some differences are...
1) yours should be painted black.
2) yours should not have the protruding light in the 10 o'clock position relative to the tach.
3) your tach should have single digits (read in thousands) rather than double-digits (read in hundreds).
4) the tach needle should be at rest around the 5 o'clock position rather than the 4 o'clock seen below.
5) there is just one switch on the left side, slightly lower than the top one seen below.
6) the stock switches should still be present in the dash
7) disregard the center dash area in the photo below. Your model is different than that.

Regarding the notch in the air cleaner housing, these two photos should give you a fair idea of what it needs to look like. I thought I had something better in my files but can't locate them as of yet.

Mike, it was a real pleasure to meet you and your god son at the track over the weekend. I also had the pleasure of meeting Dale Mathers (kiwiboss) who flew in from New Zealand. In spite of the rain, I still had a great time. That's a nice score on the tach. Last week of school... lucky you!

That's Ron Bucknum, driver of the #9 Penske Camaro. I think this is from the '69 Mid-Ohio Trans-Am race.

Bruce,

That is the engine compartment of the first '67 Penske Camaro (the car that Mark drove through the first 8 races of the '67 season) but it is after the car went to Europe. I believe the photo may be from 1969. I received that photo from Jeff Barley in England. I'm not sure if you received it from the same source or if I may have forwarded it to you.

A photo of the '69 Penske Camaro dash and interior. This is early in the '69 season due to the presence of the vinyl top.

Trans-Am Camaros / Re: Front sway bars

« on: June 02, 2011, 10:09:35 PM »

Further information, the front sway bar diameter on this car is 7/8". To make the sway bar act like a thicker, stiffer bar you would move the end link forward (away from the end and toward where the sway bar crosses the frame).

I had a recent conversation with Bill Howell who worked for Vince Piggins' group and was directly involved as the Chevy liason with Trans-Am from 1968-70. Part of our conversation touched on the subject of brakes and here is some of what he said...

"Penske ran 2 cars in the 68 Sebring, both with 2X4's. We won the Trans-am part of [the 1968 Sebring race] after getting tromped by the Fords at the 24 hr of Daytona.  We beat them mainly with a brake pad change trick I developed between Daytona and Sebring.  It took a year or more for Ford to figure out what it was.  It was a simple idea where we applied vacuum to the master cylinder to draw the disc brake pistons back into the calipers, releasing the pressure on the pads.  We took the vacuum off the brake booster.  We tapped off the brake booster thru a vacuum switch (same as used on the old Corvette headlight doors), controlled by a switch on the dash, then to the cover over the master cylinder.  [Coming into the pits] they did need to blip the motor to get vacuum into the booster.  Only the Penske cars were equipped this way, as I took the hardware with me when I went to Sebring before the race weekend to keep it secret. The system was mentioned in Van Valkenburg's book.  The reason it took Ford so long to figure it out was it was so simple, and most people thought that if you put a vacuum on the brake calipers, it would suck air past the seals and into the fluid."
