B/C-body Exhaust Manifolds, why won’t those work in A’s.

That’s great to hear, thanks everyone. For years I always heard that they would not fit thus why the exspensive header conversions seemed to come up in conversations. True that the stock manifolds could choke out upto 40hp, it was the budget way to get good torque and go from a junkyard grab-n-stab big block. If a lot more folks know that, there would have been a lot more ‘Cheap Street’ cars out there. I’ll take this info to my buddy and see what we can put together for him.
I’ll pm back in another time if I need more info. Thanks again for the tech!
