406/427 exhaust manifolds
I would love to have a pair of 406/427 bananas for my 390
F-100. Is this a possibility. Seems like the flow would be much better than the logs and better for heat control/loud headers. My Bronco is loud (sets off car alarms) and I would like my F100 to walk softly and carry a big stick. I'm getting old. What do you all think?

Thanks for the reply's. William, I have read several of your other posts on your exhaust set up. Are you going to use the standard logs? They seem awful. I hope to find a pair of these cast iron 427 jobs. If I can't, I guess I will look into some tri-y's with ceramic coating for heat control. Seems like an awful lot of money for 15 more horses? There is a lot to be said for heat control and piece and quiet too.

406/427 exhaust manifolds
I am currently using stock 2 1/4 inch log manifolds. Exhaust system is 2 1/4 inch dual to a Flowmaster 70 series with single 3 inch out the back behind the right rear tire. This combination is pleasantly quiet, but drones just a bit. I plan to add an equalizer tube under the oil pan soon hoping the drone noise improves. I believe the cast iron headers from 406/427 would really be a great improvement but I think they are to expensive and I do not spin this truck much more than 3500 RPM. I am also a member of the "old Timers group". Hate change, technology, cheap beer and progress. Firmly stuck in the 60s and happy there!
