Alternator on driverís or passenger side?

Why did GM move the alternator from driverís side to passenger side in í68? My í67 has the alternator on the passenger side and I know thatís not correct. I have a 350, í72 block with í67 heads and am considering moving it back to the driverís side. What was the reason for the move? Should I anticipate any problems moving it back? Should I leave it alone?

Re: Alternator on driverís or passenger side?

I've had mine on the passenger side for about 30 years ('67 too). Leave it there, unless it really bugs you. AAW even makes custom engine\light harnesses to flip the alternator and provide 12 volt (HEI) for the distributor all the while looking completely stock. It was flipped in '69, not '68.

I wonder why they flipped the alternator. Maybe it has something to do with the other accessories that were flipped too, like the AC.

Long water pump on the 69 and up equals different pulleys. If you put it back on the left side you will need short water pump and the correct pulleys

Re: Alternator on driverís or passenger side?

They swapped sides in 1969, as suggested if you want to put a '67 or '68 that has been updated to '69 style back to original you will need a new (short) water pump, a new belt and the brackets and hardware. If your cars build doesn't call for the stock look under the hood there are benefits from having the '69 style alt mount!

The benefits of the swap are a more rigid mount for the alternator and a shorter belt. The power steering pump probably kept the engineers from leaving the alternator on the driver side when they designed the long water pump and '69 alt bracket.

Re: Alternator on driverís or passenger side?

Thanks everyone for the replies. I knew I’d have to change the brackets, but was unaware of the different water pump and pulleys. I was considering the swap so the AAW factory fit harness would fit and I didn’t like the fuel hose so close to the alternator. My car isn’t stock so I’ll keep it as is, because it will cost more than I thought and for no benefit.

Re: Alternator on driverís or passenger side?

Your "fuel hose" should be metal tubing as it passes behind the alternator.

Funny thing about alternators, the fan at the front isn't a pusher, it's a puller. The back of the alternator is the intake. Guess where your fuel goes first if your "hose" springs a leak?
