These are a set of thru transom headers that will fit 429 and 460 big block ford engines. They have the option for 3.5" exhaust or 4". I have water lines but one needs repair. Please look at pics they show the condition quite accurate. Surface rust and a few dings. I bought them and really wanted to run them but they wont work on my jet boat. These add big hoursepower over the traditional water logs with snails.
$375 Trade for a pair of Holley 600cfm or 750 cfm performance carbs
