The 427’s had some can issues however the updated can solves that one, the 460’s and XT’s had turbo reliability issues, also solved with updated parts. I would say for my personal use an Etech 460xt, matched with a Mack 13 or 18spd and 3.65 or 3.86 rears with low pro 24.5’s and then leave it STOCK.
