Welcome to the site, Zerfetzen! Your '73 'Cuda looks like it'll be a nice project to work on. With the information you provided on the engine build, that 318 sounds like it'd be a rather beefy build for one. (a .450 lift cam is quite big for a 318. I can't remember what size cam was installed in my old '69 Charger's 318, but it had to be around that range and just sounded nasty for a 318.)
