i kno nothing and i mean nothing about this stall converter thing. i know nothing about what it is or does??
Over cammed for the heads~! .450/460 is max for those heads...Trust me...Unless your going with the old fuelie heads (461/462) and even with those heads max lift for best results is .500 lift...The 305 heads have too small of ports for that big of a cam....Parts mismatched give headaches, not fun from stop light to stoplight....That is what your looking for...Now if they were Vortec heads, go for that high of a cam...But those heads, not me...waste of money on the cam specs...bet you have fuel puddling at the bottom of the intake...not good~!
