I was told Blue Thunder makes the best reproduction and is US made. Not sure if this is all true but seems the overall casting and machining is superior to the others being offered. How many manufactures are there making this manifold? My assumption was Blue Thunder and the import, is there more? If there is something I'm missing or a better option I'd like to hear what that is. I'm building a 347 for my 67 C code Fastback and want a period correct appearing engine compartment. Any advise and guidance is appreciated.
Thanks
Shawn
