340/mag360 exhaust manifolds

Thanks Treblig. Got the manifolds on Christmas eve. They were wrapped so well I just stuck them under the tree and opened the next day. Fitted them to engine this afternoon. Was really pleased with the effort you took on the finish. Looks nice. Using conical washers under all bolts. What torque have you had luck with on bolts. I think FSM calls for 30 ftlbs. Thanks again.

30 lbs using anti-seize, except on the front and back bolts that are installed with high heat thread sealer (aviation thread sealer is what I use with good results). You're every welcome for the manifolds and I'm glad that they arrived as close to Xmas as possible. You should enjoy the manifolds for a very long time. Be sure to buy a short piece of super tight radius "MANDREL BENT" 2 1/4" or 2 3/8" J-tube or 180 tube for the area just above the driver's torsion bar. It should be 3 1/8" to 3 3/8" "MANDREL BENT" radius tubing. It will make it much, much easier to clear the torsion bar without hurting flow. Typical muffler shops crush the exhaust pipe badly when they try and make tight bends. SEE PICS

Thanks again,
