  1. Folks, I'm after a red lens cover / chrome bezel for the Park Brake Warning Light that fits in the dash down near the head light switch in a 73 Mustang? regards, Bluemac Australia
  2. I'll be watching this thread with interest. I've got a Mutha Thumpa in my 351C. The best vacuum reading I can get is 10 , and I can assure you that this is not enough for continious use of the brakes in traffic. I've since fitted a CVR billet vacuum pump and a 1litre vacuum tank to power the stock brake booster. I'm still not completely happy with the setup. I'm presently investigating fitting a Hydroboost unit to replace the vacuum unit altogether. regards, Rod A
  3. Hey there, I'm Toowoomba Qld, and I also drive a 73 Mach 1. These things pull crowds everywhere they go. While the dewds in their early stangs tend to speak poorly of our beasts - the public love them. I was at a motor show earlier this year, all sorts of classic cars there. People couldn't believe that my Mustang was so mean. A 302 is only a 351 with short con rods - easy to give it some more life. Keep it - 71-73 stangs are so rare over here. Bluemac
  4. Hi Folks, This is my first post to this forum. I've been lurking for months, but never had a reason to post. I've recently had my 351c rebuilt with a Mutha Thumpa cam, along with every other part in and on the motor. It was run in and tuned on a dyno - [my son works in Australia's top race motor shop] It only pulled 7mmhg of vacuum at idle, and even after tweeking the timing and playing with the Holley Ultra S/A we could only get 10mmhg. Clearly, nowhere near enough to power the vacuum booster on the brakes. I had to install a vacuum cannister and a billet 12V vacuum pump to feed the brakes. My 73 Mach 1 has most of the optional vacuum sucking add-ons - so I had to go this route. I have a beautifully torquey motor 420lbs at 3500rpm with a 3000 hi-stall t/converter and a 3.50 diff ratio. Brakes are critical. regards, Rod A
