Almost got my swap done, just finishing up a few loose ends. The heater hose connetion at the back of the intake on the GN engine has connections for 5/8" heater hose, which is fine for one of the heater cores connection in the Camaro, but one of them is 3/4"! I have about 4" between the two connections, is there a heater hose made that is 5/8" on one end and 3/4" on the other side? Or should I just use a 3/4" hose on that part and "overly" tighten the clamp on the motor side?
