Re: What manifolds are you using on your BB
I have the 879 and 178 manifolds, and there is a reason to use the F-body specific manifolds. If you have power steering, an 879 has a cast in divot to clear the steering box, and it is tight even with that. Both sets have the F-body specific bends to allow the exhaust to fit properly.
I have no idea how they flow, but they don't look restrictive at all. They wouldn't be as efficient at scavenging as a long tube header, but...
