Carbed LS setup with an external / aftermarket dry-sump (Dailey, A.R.E.). You get the benefit of the aluminum block, you can build any bore/stroke combination you want, and you resolve the oiling issues with the dry-sump. You get rid of most of the sensors with the carb, but you do still have to run something to drive the coils (unless you do a timing-cover distributor conversion).
Do it!
