Re: LS swap questions

To keep the stock TBI setup you'll probably have to buy an aftermarket carbureted LS intake and use a carb-TBI adapter. If you're keeping the TBI setup and not using the EFI, I'm not sure how much of a gain you'll see. I would bet money it would be worth a few MPG over a worn out small block with over 200,000 miles on it, though!
