Today I swapped my intermitent cruise control unit on my 75 Grand Am for another one from a 74 Grand Am donor parts car and it worked like a charm, pushed the button at 65mph and it stayed rock steady all the way home on the TransCanada Hwy ... it should help saving a bit of gas, lol

I am going to document the engine swap I did in my 73 LeMans. The car was originally equipped with a Chevrolet 350 from the factory. This engine ran perfectly but I wanted more power and fun after 7 years of ownership. A good running 454 became available when site founder Canadian Poncho sold his 1969 La...
