How to: GM12SI alternator on a small block

Hey Gold Duster, nice job on that conversion. I've done many myself similar swaps over the years, and they worked great, as long as I didn't expose them to high rpms too much.

I now convert my engines to run the Toyota (sorry guys) alternator and Mancini Racing sells the brackets to install them. The Toyota alternators can run at 7000 rpm+ 24/7 and they have a very low HP draw. I've never been able to wear out the Toyota unit, but the GM units, while a nice option, tended to have a shorter life cycle in higher rpm applications. Just my experience with them.

Anyway, that's a nice ride you have there and good luck with your upgrades.
