I don't have a GT-40 yet, and the time frame of getting one is directly affected by where I'm placed for my next job. But until then I'm just trying to piece things together in my head. Making lists, checking them twice... That sort of thing.
I ordered a dart (351 Windsor base) 427 with webers for my SPF GT40, shortly after receiving the motor I found out it was not going to fit with the extra deck hight. So I sold the carbs and put TWM throttle bodies with EFI which will fit. Here are a couple pictures of with carbs and with TWM.
