Hello! Thank you for allowing me on the site! I have a 1990 standard cab 8' box 2wd Silverado. Had it since '92. Original 5.7 (I call it a 350) with a few performance parts. Up until this spring, it had a Procharger blower on it. It now has an Edelbrock 600scfm carb! Look forward to Hanson's out on the sight!
