I still have a 260 in my Tiger. While at Tiger 50 last summer, I met a Tiger owner from Sweden, Anders Weiter, who builds Vintage Race Mustangs. He still has his 260, but with 302 internals. Comes out about 272 ci. He said the best part is it has lots of bottom end torque - 4th gear in town cruising!! Another alternative for "stock" appearance. Peter
