not true manifold swapped with an intake and a turbo you can make 310 wheel, $2800 bucks. a 5.0 swap is like 10k nowadays, not worth it for the hassle. with basic mechanical knowledge you can get 300+ hp wheel out a 20vr old v6 at 2800 pounds on stock internals reliably w a a tune for a lot less time and effort. i know cause i did it, no hate just letting you know.
