So as far as exhaust manifold upgrades over stock manifolds we should be looking for in this particular order. Talking about a 1967 and up a-body (in my particular case a 1968 barracuda with power steering)
It may have been mentioned somewhere about wether or not certain manifolds will or will not work with power steering other than the 340 or 273/318 drivers side exhaust manifold
1: Both driver and passenger side 68-71 340 exhaust manifolds.
2: Drivers side 340 exhaust manifold 68-71, 96-98 JGC passenger side exhaust manifold
3: Stock drivers side 273/318 exhaust manifold, 96-98 JGC passenger side exhaust manifold
4: Always turf the passenger side exhaust manifold and at minimum install 96-98 JGC passenger side exhaust manifold as they are plentiful and cheap.
:lol:
I think someone led to the fact that a 318/360 magnum/JGC driver side exhaust manifold may work without power steering and with a bit of modification/grinding???
Please someone correct me if I am wrong.
