Just check the milliamp ratings.

You may find it easier to get one made if you have a special requirement. That's what I did for my TR7 and it actually turned out cheaper than a factory spec one. I'm in the UK but I would have thought it wouldn't be all that different in the US.

try a perfomance catalog. jg smmtt. or call a dealer or parts house ask them if they list a higher amp alt. there is an option of finding a shop that rebuilds alt & starters. they can prob increase the amps for you.

Nope. That is what my HOSS is. Had the same one eveyone else does. However I was thinking for some reason that the 6 liter trucks had a higher rated one.
