this book came with my car and have just skimmed through it i was wondering how relevent the information was in this book nowdays and where has the reasearch and development excelled over the 35yrs since it was published those guys were running low 11's and 12's way back when... just awsome:thumb

Very good book.
Most of the basics are still relevant.
I still read through it about every 6 months or when I want to find
some obsure bit of info...cool photos on the back.
