Where can you find a wiring diagram for the dash of a 1970 Pontiac Firebird?
A 1970 Pontiac Service Manual will have this info in it. You can find them on Ebay or one of the literature places on the web.
I restored a 1970 Pontiac Tempest about 15 years ago. I purchased a book that contains very detailed diagrams of every aspect of the car. If you're still looking for a wiring diagram, I can try to dig out this book and find it. (There's no date on this question, so I'm not sure how long ago it was asked)
The Pontiac Firebird Trans Am was made by Pontiac, which is a division of General Motors. The first (1969), second (1970-1981), and third (1982-1992) generation cars were assembled at either the Van Nuys, California or Norwood, Ohio plants while the fourth generation (1993-2002) cars were assembled at the Sainte-Thérèse plant in Quebec, Canada.
The man most credited with it is Pontiac engineer Herb Adams. He had been head of development team on the PFST (Pontiac Firebird Sprint Turismo) in 1967-68. The special suspension parts developed for the PFST were used on the first Trans Am in 1969. Adams was head of special projects for Pontiac until the mid 1970's and raced Firebirds (and later his own renditions the "Fire-Am" and "Silverbird") in SCCA competition for several years.
Mustang GT Cobra Its sporty, its fun, its a muscle car, and they usually run around 24,000 new and 14,000 used. Stay away from Ford, they typically have fatal flaws with their engines and electrical systems. This is due to lazy construction. Most MOPAR muscle cars are going to cost over $30k although they were known as "clunkers" back in the day because they were made from cheap metal that often rusted away. Quality and…
Do the front springs and motor mounts need to be replaced when replacing a Pontiac 301 engine with a Pontiac 350 or 400 or 455 engine for a 1979 firebird espirit?
Yes, the 350,400,or 455 will out weigh the 301 by about 200lbs, so the front end will sag under the additional weight. Depending on the year of the motor you are swapping in you may be able to use the stock mounts. 1970-1979 Pontiac V8s had five bolt bosses per side and will bolt up to the 301 mounts. Pre '70 only had two bolts per side making a mount swap nessary.
