Just did this actually. I got my chrome chevy alternator from Mike Forte from Forte's Parts. You have two options (that I know of) when it comes to mounting it on a small block. You can call Mike and order the alternator and his mounting kit along with the pulleys so it is nice and simple. Or, if you are like me and had a March Performance alternator bracket laying around, you can use that. The only thing you need to do is drill out the two bolt holes on the chevy alternator to accommodate for the larger diameter bolts the March bracket uses. Hope this helps.
