I have come into posession of a '69 429 that needs a little TLC

. I want to stuff it into my girlfriend's 79 Bronco. Other than some ignition headaches that I am expecting, (and a severe tire frying problem

)what other issues can I look forward to? And has anybody else pulled the 351M and put in a 429/460? WHat about the transmission? I presume it has a C-6 in it. Will it mate to the 429?
