Great discussion going on here. I am no longer even considering the engine swap in my cat anytime in the foreseeable future, because I just picked up my winter/rainy day driver today, a '79 Bronco just like I was hoping for. Between the minor maintenance and upgrades I already have planned for my Cougar and a handful of things I know the Bronco needs (and probably many I don’t know about after just an hour of driving), something as major as an engine swap is totally out of the picture. Though if the day ever comes that I wanna look at a souped-up 351 for my cat, I’ll already know at least a bit about the engine since the Bronco has a 351m.
Good times.
