I need to find a quick solution to matching up some headers to a Backdraft with a Windsor 351 (Roush 392AL).
Can I find a stock (rather than custom) header to fit either between a Backdraft firewall and the Roush 392AL, or am I better off getting a stock or custom header that will point the collector straight down to the ground below the 3rd spark plug back on each side, and width will not come too far off the block (less than 3.75"), yet provide for spark plug accessibility?
Time is of the essence, as everything else is done to start the engine.
Note that the Backdraft Cobra is being finished off in the Miami area.
Thanks --
