As many of you know I am assembling a new P400 6.5 engine and Bowtie 700R4 transmission for my M1028 rebuild. Every part on the engine is either new or rebuilt and restored to OEM condition. I am not robbing parts off my existing CUCV engine, but instead fitting the new engine with its own parts and accessories. I am now at a point in the process of deciding what to do about alternators. I purchased a pair of used alternators from a fellow SS member up in Pennsylvania who assured me that the alternators were rebuildable, however I just opened them up and they are rusted beyound repair. Looks like they have been sitting in a field somewhere exposed to the rain for years. No way are they going to be rebuilt, restored, and installed on my P400. Sorry, I'm just too picky.
So my question is, are there alternative new Delco alternators which would be a direct bolt-in fit? I went to Delco's website http://www.delcoremy.com/find-a-part/product-details/1100080 to make sure that the 27Si was indeed obsolete, which it was, however the page also had a link to Upgrade Options. When I clicked there, a 22Si replacement unit, part #19020310, seemed to suggest that it was a direct replacement. This 22Si unit produces 150 amps. But then on the same page, three more Delco units were listed as Upgrade Options, a 24Si 160 amp model part #8600310, a 28Si 200amp model part #8600313, and a 170 amp model part #8600126. Has anybody had any experience with these? I have sent an email to Delco's technical service department to ask for clarification, but don't expect to hear back until after the holidays.
There are a couple of guys on Ebay which occasionally offer "new" 27Si units, and the photos always look great. But when I read the fine print, I'm not so sure. And after I endured the deception from the SS member in Pennsylvania, I am a little gunshy to say the least. I would rather continue to spend my daughter's inheritance and have new units if possible. And I like the fact that the new Delco units are rated for higher amp output.
Thanks in advance for comments.
