I just recieved my 4 x 48 IDA webers with a 'cobra' inlet manifold. Looking at various pictures of engines in the GT and the parts list in Legate's book, it looks like the webers should all be sitting facing the same way.
If you looked at the engine from the rear the right hand bank of webers have the fuel connection to the left side (between both rows of webers) and the left bank fuel connection is also on the left side. This means the fuel line should run through the middle of the webers, loops around the back and up the left side (still viewed from the rear of the engine).
The manifold has 'cobra' written on it in raised letters in the casting and there are two raised bosses, one central and one to the rear which are used to connect the linkage system for the webers.
Is this orientation correct for a GT MkI? also I think that original inlet manifolds had no bosses for the linkage and the letters 'FAV' on the front of the manifold. If i'm fitting a cold air box is it correct that the linkages are held in place by the bottom of the cold box?
Finally do you think it would be possible to use some 'aluminium filler' to replicate the 'FAV' letters? has anybody tried this? (the plan is to grind away the 'Cobra' letters and also the 2 bosses which held the linkage system.
BTW I will post a picture of the setup this evening to clarify. Oh and I also got a rather nice Aviaid pan for the soon to arrive engine will get some picks of that also.
And the big news is that at 6' 2 1/2" I had a chassis fitting last saturday and I officially 'fit' into a GT40 monocoque....... that was a tense entry into the car but I have ample leg room and with a Gurney bubble headroom is fine. If I didnt fit I was going to sell the chassis and move over to the dark side and build a P4.......
Oh and one final thing anbody know who make the phenolic spacers in the UK for the webers which helps prevent heat buildup in the carbs?
