Re: SMOG LEGAL ENGINE SWAP TO LS yesterday passed!

the trans thing is crazy how the hell does that make a difference in emissions. fuel economy possibly if you kept say a th350 or 400 but emissions aren't going to change. I wonder how they deal with replacement engines on stock cars or say if this engine failed can you just swap in another 5.3? so many more things I wonder but im in ky so no point in me asking.
