sounds like there are fans of both the P.P and the EDDY. while I am sure the professional products manifold will bolt on and work fine, I wouldn't personally own one just for the simple fact that they are made in china. to me a large part of the pride and fun of owning and restoring a vintage muscle car comes from the nostalgia involved. collecting original equipment "American" hard to find parts and adding quality nostalgic speed parts that add to not only the cars performance but also to its history and even its resale value. my cell phone and TV may be made in china but you will not find a "zingfu" distributor under my hood no matter how much money it saves me.. todays cars are for the most part "throw away cars". they will never be restored and no one will be sad to see them finally disappear from the road one day with their sun rotted plastic dash boards and underpowered imported 1.8 liter engines. nostalgia is what keeps our vintage US vehicles alive and drives us to spend so much more money on them than we should. think about it, if 2 identical cars were sitting next to eachother at a car show and you popped both hoods to find one has an original 440 six pac intake and some polished M/T valve covers and an MSD and the other has a chinese made no name intake, chinese made distributor, a pair of poorly chromed chinese stamped steel valve covers with partly melted plastic 440 emblems glued on them , which would you take a picture of and dream about owning?
