Some notes: first, OldRide.com doesn't list the 426 ci V8, which was extremely rare anyway (up to 57 may or may not have been built, and only 7 are thought to have survived). Second, Wikipedia's pages (both for the car and for big-block Chevrolet engines) lists it as displacing 427 ci, but also as having a stroke of 3.95 inches, or 100 millimeters, which when combined with the engine's 4.312 in./109.5 mm bore would give a displacement of almost 460 ci. I suspec it's a typo, as punching the 3.65 in. stroke listed on 348-409.com into a displacement calculator yielded the 426 ci figure I ended up using. Third, the T-10 may not have actually been the only true 4-speed manual available, though it was the one used with the 426/427/whatever. Finally, the Wikipedia page on this car is confusing, incomplete, and sometimes inaccurate, which caused me much frustration and time-wasting throughout the process of making this thread.
