Go look at the link I posted earlier in this thread. You get, 2x more power, a longer warranty and it's cheaper than the 200 Alternator. DC Power Inc. takes only new Denso alternators and custom machines new pulleys, front and rear cases to make them fit other applications. For the hundred, no wiring mods are required just a slight bit of grinding on the PS pump bracket. None of the other HO alternator places post idle or hot idle ratings, nor do they load test there alternators, many simply use a smaller pulley and drive the alternator faster to increase the output causing them to fail sooner than OEM.
The pics are not showing in the comparison section of their website but it's worth reading!

Kirk,
Did you use the stock cables for your 270 alt. or do you need to use larger ones for the upgrade?
Thanks
Ken
