How is it attached? What pulley setup and alternator?
LS3 setup, but Y- or camaro isnt specified... dunno which.
from what I've heard, all alternators are the same depth/bolt spacing, with slightly different ratings/pulley sizes
it's just a mockup but the alternator bolted to the belt tensioner bolt hole on the waterpump, and the pulley offset is supposedly pretty much spot on with no spacers.
the 2nd bolt hole on the alternator would need to be mounted to secure the alternator, probably via a turnbuckle to tension the belt.
bolting directly to the block and head have been mentioned. im trying to figure out the details still.
