Hello
im looking at a 77 esprit that the someone made to look like a formula and swapped the motor however im not sure what the motor is now, the guy had advertised is as a 77 formula 400, but the vin and tag tell a different story, vin and trim tag both say is a 1977 esprit, originally a 301 according to the vin, 2T87y7N, the only thing i could find on the motor was a XF stamped on the passenger side about a inch below the head, right next to the water pump, unfortunally xf shows for 10 different motors everything including a 301, 326, 350, 400, 428 and a 455ho, the intake was changed as well so i couldnt get numbers off that, and the headers that were on the car made it impossible for me to find a displacement stamp. the owner claims is a 400 but he always claimed is was a numbers matching car, and neither of the 301's that fit the xf code fit a 77 only 78 and 79, is it possible it was a late model 77?
