Also.....you said somewhere you could have gotten a thicker ear on the alternator so as not to have to use shims?
I know you mentioned Alternator Pulley diameter somewhere but to put all in one post, what Alternator Pulley Diameter did you end up with?
I think you also mentioned you went with 180 amps?
Have to study your solutions regarding the Alternator wiring/connections one more time. I assume you ended up using an adapter for the OEM Alternator Connector to fit the Billet Aluminum Alternator? Or you modified the wiring yourself but there are Connector Adapters available like WVZR-1 suggests?
Anyway.....you know where I am going with this......I definitely appreciate what you are doing in the LT5 restoration

I am hoping to have the plenum on VERY soon. And im fairly certain of that after taking.. oh.. 4 months
!! I will report back on fitment with lots of photos for sure.
Yes with regards to the shims, SInce the billet covers are custom cut per order Im certain you can specify thickness. I took measurements and can post them here, but if anyone will order in the future you could measure your ears on the factory alternator and send them to the manufacturer. I will be sending my photos and measurements to DC so hopefully they make that change in the future.
ALternator pulley I believe is 2.5" VERY close to stock. DC suggested a smaller pulley but I told them I don't have a pounding system and I don't often even turn it up too much I really just want a better alternator and to have a better functioning charging system. I was told by all manufacturers that the alternators can easily handle more peak rpm than the stock cs144 which a few even had a few not so great things to say about lol. I told DC I have bumped up my idle rpm already, and have a higher limiter set so I felt a 2.5 pulley would work and they agreed.
Someone also mentioned pulley alignment. I stood both alternators on their pulleys and the tabs are in perfect alignment on both ears so I would assume this is a simple way to know if the pulley will be in the correct position. I took pics and can post if needed.
As for wiring, the harness they provided plugs into the new alternator. One wire has a ring terminal already heat shrinked and crimped. This goes to the positive post. the other wire simply needs to be connected to the brown wire on the original harness plug. ALl I did was unpin the gm plug. cut off the pin end. tied it into the wire on the harness and soldered it together. ANother option would be to snip the brown wire, add a butt connector and then if there was a need to switch back it could easily be done by unplugging it etc.
Here are some photos in case I wasn't clear about the wiring.
harness DC provided. Blue has a ring terminal already. yellow I had to strip with a wire stripper...
right before soldering
I added heat shrink and then taped it onto the oem harness. I taped the plug downwards and out of sight so it sits a bit below the alternator and is still there.
Close up shot of it all.
