351 Windsor Headers
« on: Today at 03:02:38 PM »
I have a 1969 Mach 1 with 351 Windsor and FMX trans in left hook but my exhaust shop was not keen on fitting a set of headers because he said they needed too much modification and will burn the plug leads. His name for the heads were GT40 and said previous attempts at fitting headers has failed. Nobody seems to want to guarantee a set of headers will fit this engine without mods or complications. Has anyone else struck this problem and the remedy. Cheers

  Check the heads on the end and see if it stamped GT40P. If so you'll need these.  https://www.ebay.com.au/itm/Ford-Mustang-Extractors-Headers-289-302-347-GT40P-Heads-1964-1965-1966-64-65-66/271699320770?hash=item3f428a9fc2:g:FrsAAOSwYlJW6fiX
