Questions on 5.7 motor

Hey new here, planning a swap for an older Toyota pickup of mine. Wondering if anyone knows where I can find detailed info on the 5.7 V8 year differences. Or if anyone knows a lot about them. Let me know and I’m glad to be here!

 

What do you mean "year differences?" Do you mean changes to the engine or changes to the Tundra as a whole by model year?

You might try edmunds.com to see model year changes, but it may not be complete. As for the engine changes, there's not much. The only change I am aware of would be when they added flex fuel capability, and then when they later removed it. Beyond that the engine hasn't changed much.
