the '05 should have the Super E. that is the only year that came with the super E because of EPA regulations stepping on performance. along with the different carb, you will have a plate between each jug and the intake runners that restrict the air/fuel flow. these can be pulled and cut to a size that will match the fuel runner and help performance. this would be a less expensive way than trying to find an intake manifold that would fit with the extra length to replace the restrictor plates.
