Your wasting a lot of money on STUFF that won't give you the performance your looking for and most likely will take away from the range you will be driving around in ----I'd really suggest you find a late model LIFT OUT engine package and convert that car to newer modern performance /economy------you can get complete liftouts reasonably priced from salvage yards and they include wiring, ecm, accessory and accessory drive packages plus exhaust manifolds that fit, won't leak, etc--------look for a 6.0 from late suv/pickup or Camaro
