These high output alternators that we sell are a Z Specialties Exclusive. They are brand new, not a rebuilt item. We have them custom made and we modify the case so it makes them a plug’n’play unit for your Z. You do have to change the ends of the cables and they come with the alternator. The T plug in doesn’t get used. NOTE: A special heavy duty belt must be purchased with these units. See listing for your year.
For the 75-77 units your core must have intact contact points in it for the fuel pump. For the 78 units it doesn’t matter. A 125.00 refundable core charge will be added to your order at time of checkout. If your lid is damaged or missing there will be an additional charge.
Each unit is fully rebuilt, recalibrated to original factory specs and tested. A 125.00 refundable core charge will be added to your total. Your core return must be the 4 bolt style and full intact with a good lid. For 3 bolt style see listing.
If we don’t already have a pulley in stock it takes about 2 weeks to get one back from the rebuilder. The 70-72 crank pulley has 5 timing knotches on the right side of the keyway. The 73 timing marks are on the left side. We only set the marks on the right side when rebuilding so for the 73 cars you’ll need to change the timing pointer. A 200.00 core charge will be added to your order at the time of checkout. Help us keep the core program alive. Cores are rare. Please return your cores to us immediately.
