Do a search. Tons of info here on these swaps. U can run a few different kits. Basically u need to set up a budget and see what u can afford to do. Idealy a 408 would be a good bang but a 393 will also get the job done for cheaper..... Can also be done on a healthy stock stroke 351... All depends on what u can afford and how good ur suporting parts are. (transmission, rear, suspension)
