are shumacker headers restrictive?
Joe hit it on the head by saying that 500 or less HP the Schmachers are just fine. Now if you're looking for all the muscle that 440's got hidden then a shoe horned set of TTI's and 800$ would be the route. Remember though, high flow headers work best if the heads and intake and carb are up for the party, Ka Ching goes the cash register.
Yes, a good set of headers do work well with decent heads, But you will be mighty surprised how well they work with "stock" iron heads too, Iron BB heads have a poor exhaust port, so they need all the help they can get, my gains were done with "bone stock" 906 heads with the stock size valves, casting flash & all, i even ran a set of 2.00" hooker FWs on a mild 446 with great results.
68dodge, sure you can get into the 11s with those headers un-corked, but i'll garuantee you will run mid 11s with & alot better MPH with a good set.
Me personally will not spend 800.00 on a set of tubes, even the TTIs have fitment issues, i love the FWs & thats all i ever use, unless you have a factory 340 car, then chop away, because your not hurting the value any on the adverage A body, if its a factory slant 6 car, forget about it, it ain't even a question whether to cut the holes or not, have at it, so unless you can find a set of used TTIs (they do pop up 4-sale), FWs all the way.
