I have a complete D1-SC kit with less than 15k miles from my 2000 Silverado. The oil has been changed every 6k miles per Procharger's recomendation. It is pullied for 10 psi but makes 11.5 or so right before it shifts on my cam only 5.3 with 1 3/4 headers and exhaust and a Fast 102. It's still on the 6 rib stock accessory drive like the kit comes. I'm only selling to upgrade to a F1-D headunit to feed a forged LS2 I'm building now. I'm asking 4000 and I'm located in Montgomery AL, willing to ship on buyers dime
