/6 swap to 360 questions???

2 brl and 4 brl throttle cables and kickdown linkage differ. If you're going with aftermarket carb you may as well plan on aftermarket connections.
Got the car type oil pan for the 360 ? You may need the offset oil filter adapter too.
The suspension and steering is a different project for a differnt day. You dont even have to change the torsion bars right away.
