I've had a number of 351M's over the years. It all depends where you want your engine to start making power, this will determine your parts. By simply changing out the stock cam and gears to a mild rv cam makes a world of difference being these engines were very retarded due to emission controls. Also by upgrading to an aluminum 4bbl intake and a Holley 650-750, just make sure the intake you buy is suited to your application (rpm range). True dual exhaust is a must. As well if you want to make more power you can do a complete rebuild. Buy a set of flat top pistons, either get your heads done or find a set of aluminums(which are getting rare).
