ferox Posted March 13, 2008 Share Posted March 13, 2008 If anyone is planning on doing the 100 amp alternator swap I have cross-referenced some vehicles they came in: 1980 Chevy K5 Blazer or Truck w/ a V8 1980 GMC Truck or Suburban w/ a V8. There were a couple V8 sizes but they both take the #7157 alt. They also came with a 63 amp part #7127, so make sure you get the 7157. When I called my local parts store with the part number they said they didn't have it, couldn't get it. I called back with the year/make/vehicle and they had three in stock.

Nug Posted March 14, 2008 Share Posted March 14, 2008 I think they came in 78-79 cadillacs also. I just put one on my Triumph Spitfire. Link to comment Share on other sites More sharing options...
TheLoyale Posted March 15, 2008 Share Posted March 15, 2008 Now with the GM 100 amp's you would need to change the pully right? Because those had serpentine belts.. Can you just take the pully off the old/stock alt? Link to comment Share on other sites More sharing options...
ferox Posted March 15, 2008 Author Share Posted March 15, 2008 I took the pulley off the stock core alt I traded in just in case. The 100 amp GM alt. I got had a v-belt pulley. I ended up needing to add a spacer to get the pulley to line up with the crank pulley, so I tried the fitment of the old stock pulley and it was exactly the same.
