Low budget cruiser id throw the 360/727 in and start cruising if they check out fine. Wont be a rce car but will sound good and cruise just fine. 727 is a stronger tranny w a lower 1st gear for a hotter engine later. Have to put alot more money into a 904 to get them to hold up to considerable hp. Yes it would be a little lighter but if your not racing all the time who cares. IMO 904s are junk. blew up 3 in my 450 HP duster before going w a 727 been 6 years w no problems.
