About ten minutes if you've done it before. Not much to it. Disconnect the battery, remove the mounting bolts and wires. Installation is the reverse, except for tensioning the belt.
Weight on my Pontiac LeMans Sport registration is 3800
1970 Pontiac catalina coupe and sedan had a standard 350 255 horsepower the 400 was optional rated at 265 horsepower
With standard equipment, MSRP $3,985.
about $150 for the alternator and 1/2 hr labor or shop minimum charge - my guess $215 - $225
Around $400 for a new install.
There are plenty of different ideas on how much on should expect to pay for a 1970 Pontiac GTO in good condition. However, it is around 50,000 dollars at the average.
Fully dressed, with alternator, power steering pump, etc about 650-670lbs.
$55.00 for the part and $75.00 to install. So $130.00

The alternator itself with cost you about $60-$75, depending on where you go...if you install it yourself, that's it. If you have it installed, figure another $100 dollars.
Depends on the make, model, & year of the car, who installs the alternator & battery, and the type battery you buy. Most auto parts stores will install a battery for free. Batteries cost from $60 to $250. Alternators cost from $65 - Up. Labor to install an alternator can be from $75 to $225 or more.
Depends on the make, model, and year of the vehicle in question which you failed to list. Call your local auto parts store and they can tell you what the alternator will cost you. Then call a trusted mechanic and ask them how much to install it.
