I'm new to this site and just want a little info. I'm this close to buying a 98 ss (yes vin matches) and I want to know what the top speed possible is on the 4.3? Vin code W. I will be adding open exhaust, cold air intake, throttle blade mod, and a hypertech programmer. Plus H rated tires. So will it do 128 or above if I set the programmer to that? Tired of people on full size forums telling me to do a 10000 dollar motor swap. I want it as is, original. Thanks!
