thinking about getting a 429 to put in my 73. its has the fmx now, planning on putting in a t5 someday. any thoughts? should I leave it with the 351c? my current 351 is not in real good shape, ide need new heads and the cylinders to be bored out a bit so I figured it would be better to just get a new engine all together. is it worth changing over to a 429? will my accessories bolt up? anything I'm not thinking about? I'm aware that a heavier engine will incurre a slight loss in handeling but I figured that since a 2000 lb cobra could handle a 427 just fine why not a big 73 coupe.
