I would like to upgrade my 69 442 year internally regulated open face alternator to a higher output one. I've read through the alternator upgrade sticky but gathered a 1990 Delta alternator was suggested. When I try to find one on EBay or Rockauto, I get a picture of a 3 point universal alternator with a ribbed pulley.
Does anyone have a part number I can use to order a higher amperage (65-100 amps)?

Thanks, Randy

 

I used this one several times off a 91 corvette 105 Amp. I swap the the pulley from the serpentine to the v groove. Works great

 

Thanks Qwik, that was quick��. I ordered one just now. Much appreciated!

 

I was tied up when I responded and forgot to add this pigtail adapter will make it an easy swap.

I am glad you added this post. I was going to say "his harness connections are different than the 91 Corvette".

 

Ordered the connection as well. Thanks guys.

 

FYI, the 1990 Delta was FWD. You want the alternator from a 1989-1990 Custom Cruiser, which is RWD and used the 307. That is a 105A CS130.

I'm not sure what additional equipment you have that requires a higher output, but personally I'd keep the open face front housing, and swap it onto a higher output 12SI for appearance sake.

 

Thanks Joe, didn't really need 105 amps but 37 or so wasn't cutting it. I will keep the original alternator for posterity.
