That is really up to you and your wallet. Obviously you can't beat brand new, but I wouldn't worry about a used engine/trans with 20-30-40k on it either. An engine with 75-100k on it, I'd pass on.In your opinion would you buy an engine and tranny from a donor with miles or strictly new on each? Looking for an L83 or L86
Your going to have a hard time getting a crate production L83 or L86 they are not offered yet as far as I know. Currently the Gen V production LT1 is available through Chevrolet Performance and it is quite an engine, all the Gen V's are.In your opinion would you buy an engine and tranny from a donor with miles or strictly new on each?

14' was a good year because the Gen V engine was introduced and the LS3 as well as other Gen IV's were still available; so you have a choice. It's actually a Federal law regarding the engine year so all the states are subject to it but not all do not enforce it.Robbie you just brought up a question for me so my jeep is a 14. Do I need a 14 or newer engine to satisfy the state like California? Even though I'm in Washington state.
I'm looking at (2)5.3 one at 7k miles and another at 9. High 4s to my door with 6l80 or 6l90
