MAC suck. Stay away from any individual flanged headers. BBK's are fine. Mid lengths don't fit without modification, about the same as full lengths.

I know BBK is rather popular for our cars as well, but I'd like to stay away from them. Did I hear something about mid-lengths fitting as well? 1 3/4'' mid-lengths would be much sexier.
Concerning FPA, yes, I ended up spending two or more hours on the phone with him when I was originally working on the 460/panther wagon swap. I just hope I own something someday that I can actually use of his, the products I have seen of his are nothing short of art.

The couple sets of BBK headers I've installed have fit nicely. Access to all the bolts with a ratchet is a nice feature.
1 3/4" tubes is also bigger than necessary most of the time. Production heads seldom need more than 1 5/8". Stock un-ported heads actually do best with a 1 1/2" header. Dont need or want a bigger primary tube than the exhaust port is, it will slow down the exhaust gas and have a poor scavenging effect. Net result is a loss of torque.86 Lincoln Town Car (Galactica).

This is turning out to be a new height in for the build. MAC is the only company with a 1 3/4" primary on the market. I guess I'm slightly f*cked here, I'm not about to spend the $1200 on some custom stepped coated headers yet, and my only other option everyone is slaying. Anyone else seen 1 3/4" primary shorties by ANYONE? Chrimeny...

So when ya gonna fill us in on the combination? Wonder how similar it is to a Brodix-headed 351 with a big mechanical roller that I tested at nearly 600hp NA on the virtual dyno.2012 Mazda5 Touring | Finally working on the LTD again!

Well, my engine builder is waiting on the timing cover I'm getting blasted and powder coated right this very minute. After that, I'll send it over and he'll be able to slap the oil pan on. It should be in the garage by next weekend, so I'll take some pics of "THE PHANTOM BUILD" so everyone can drool for awhile. I'll divulge a little bit I suppose, I really wanted to wait, but we could all use some excitement around here.

I'm running stainless steel allen head bolts and stainless steel lockwashers on my BBKs. Had one loosen up since I put them in spring of last year. I bought 50 of each for half the price of one set (16 pieces) of brand name header bolts.Builder/Owner of Badass Panther Wagons

Interesting that you're able to get enough torque with Allen head bolts. Sounds like a potential improvement over my situation of having to use an angle-head wrench to reach my 7/16"-hex header bolts on the Flowtech headers (Mustang headers have been using regular Grade 8 bolts with a 9/16" hex). What size Allen head do your bolts have?2012 Mazda5 Touring | Finally working on the LTD again!

Why would it be tough to get torque? I use a socket and a wrench. I made a nice socket for the really tough ones by purchasing a 5/16" universal 1/4" drive socket and cut a short piece out of a 5/16" allen wrench to fit in it. Works great.Builder/Owner of Badass Panther Wagons
