im trying to decide if i should just take the easy route and use shortys or the possibly dificult route and go with long tubes. the car they are going on is my 69 galaxie, auto trans floor shift. the car is bagged and the frame lays on the ground. so does the transmission crossmember. so my question is. in relation to the lowest part of your trans xmember (right below the trans) where do the collectors sit? higher? lower? even? if lower, by how much? if higher, by how much? the motor is a 351
