JacMac asked me to post this folks-
Re Flat plane cranks, very few if any GT40's were fitted with these, thats why they went with the crossover 180° setup you see in most pics, even the INDY Ford of 255 cu in & larger variants as used by McLaren were two plane items with crossover exhaust systems.
There are pics of the Coppins car with what appears to be a crossover set of headers on the TRS site, they are in a thread titled 'The Steve Twist Collection-Jack Inwood photos' post #s 75 & 80. The thread is about page four under general discussion at moment. While not clear in the pics I think the pipes on LH bank cross under rear of pan into collector/s on RH side ( car being LH drive this would have had most room for pipes).
Im sure I have an article & pics of the engine bay for the same car being fitted with a new motor for 'Big Pete' by John Shepard in either a 'Wheels or SCW mag ' from OZ circa 1965/66/67.
