[Chevy Silverado Alternator Replacement]

Thanks for the advice.

[Chevy Silverado Alternator Replacement]

I have a 2007 Chevy Silverado VortecMax edition. Does anybody know the amperage of the alternator? It's a 6.0 V8, not a 4.8 or a 5.3 V8. 

[Engine rebuild]

Hi, I live in California, specifically the Los Angeles area. I'm looking to have an engine rebuild on my 2007 Chevy Silverado VortecMax. It's currently at 177,776 miles on the odometer. When I reach 25 MPH, the truck starts to vibrate. Does anyone know a great performance auto shop that specializes in pickup trucks? If you do, let me know.
