Hey Trebling,
I've got power steering. What are thoughts on manifolds knowing that, use the 273 manifold for drivers side and donor 360 (with a touch of grinding) on passenger?
With power steering your probably going to be stuck with the 273 on the driver's side. Using the 360 on the passenger's side probably wouldn't help much because it would cause an imbalance in you exhaust (from side to side). It was also require redoing the down pipe on one side which would have to be 2 1/4" pipe then you'd have to connect that to the skinny stock pipe. I don't think it's worth it!! But it's your car.
