hello i'm new here and i wanted to ask a few questions to anyone who has done a 5.0 swap. first, would the stock 88 cougar exhaust manifolds fit in my 78 cobra ii? second, what is a better tranny, c4 or aod? and finally can i use the fuel sending unit off a 74 v6 or is there something wrong with them? i have two 74 v6 coup's and they both have a return line. thank's in advance.
