67.85.83.70
AI have a '67 CS Conv, 330 Ci, with some kind of headers ( may have been reworked)( long collectors) and dual exhausts.. 2" and flowmasters 40's .
The left header has been extensively beaten upon to clear the frame and suspension, so much that at least 2 of the downtubes are seriously compressed. The car runs fine, never an over heating problem, plugs run clean and even, though the right side brake line runs against the frame and very close ( 1/8th inch) to the down tube, I have been on 200 mile trips and there have never been problems with the brakes. The headers even clear the starter.
The question is... has anyone ever converted a stock left side exhaust manifold for use as a dual exhaust... What is involved in the conversion? Will I lose or gain any significant benefits from converting over the questionable duals I currently have?
I don't wish to get new custom headers due to the expense, but might be interested in a left side manifold, if available and cheap.
Thanks for you input.
