Some pretty interesting intake and exhaust manifold descriptions and photos. The writer of this post is not me and it will apparently take some R&D and registration at the site to find him. John Forney is apparently involved in both options if he still lives at the posted e-mail address. I and club members Bruce Toelle and Scott Tozzi all had our 300's at the Wine Country Mopars show Sunday and each of us brought home trophies in various MoPar classes. Not enough 300's there to make a class of our own. A great venue at the Sonoma Jacuzzi Winery. Keep this in mind for next year. And, yes, it is the same family that made and marketed Jacuzzi tubs; and no, the wine was not prepared or served from one! C-300'ly, Rich Barber Brentwood, CA 1955 Chrysler C-300 Yes, both the popular "truck-style" 4-bolt exhaust manifolds are being reproduced by John Forney jwforney@xxxxxxx and the '57-58 Chrysler flat-sided 4-bolts needed for the 392 in the Chrysler 300 stock chassis is also being reproduced with John's help and sold by me (send PM to me if interested). The original truck manifolds have been popular with hot rodders and have been going up in price but many were very abused from their years on trucks and typically have broken mounting ears or have cracks and repairs from extreme heating in high load conditions and many are warped. So John Forney reproduced them. Super high quality castings and he is the machinist that finishes them. He also sells the head pipe stubs to start your downpipe. Besides the trucks, this is the exhaust manifold that Carl Kiekhaefer legally used on the '55-56 Chrysler 300 race cars in NASCAR because it is a factory part and it clears everything in the car chassis. The '57-58 manifold repro I offer had to be created by the factory as a response to the new-for-57 torsion bar chassis. The old truck 4-bolts would not clear the right upper control arm and the steering box. By slightly flattening the casting of one ram's horn the clearance was gained. This was accomplished by the mid-57 production year and became an offering on the '58 option list included in "the 2.5" exhaust system" option for all 300s and was standard on the cars equipped with electronic fuel injection. Summary: If you want 4-bolt ram's horn types for your 331-354-392 Hemi in your hot rod, John's manifolds are perfect. If you are building a '57-59 factory chassis Mopar with one of those engines in it, you will need my flat-sided 4-bolt manifolds for clearance.

At Carlisle, I was told by someone in the Chrysler Products Club that "someone" in the "western 300 club" has reproduced the "4-bolt truck exhaust manifolds" . He wasn't sure if they fit 300B or 300C,D. Sorry to be so vague. Does anybody know any particulars or if this is even correct??
