Had our 03 Impala for about 2 years now. It's a base with the 3.4. Also have an 01 Silverado ext. cab 2wd with a 4.3, 88 Shelby Daytona and an 82 Dodge Ramapge with a forged 2.2 turbo swap. Don't really have anything done to either chev's since we are still paying on them, but a set of enkei 18's on the silverado for now.
