1. Put in anything you like, register it "not in Kalifornia". Nevada, Oregon, etc.
2. Put in an LS engine / tranny and then just don't tell anyone. FYI, an emissions sticker that looks exactly like the MB one on the radiator bulkhead can be produced that has been updated to show the equipment present on the car so the emission inspector is only looking for the stuff you want him to look for.
3. Put in the LS engine and enough emissions stuff to pass visual inspection. FYI, a GM computer required to run the engine and to be read from the OBD II port can be obtained that *never* throws an emissions code.
MB 560 engine is 452 pounds undressed (e.g., no alternator, etc.), LS engines are about 394 pounds dressed. LS engines can be obtained from about 305 HP (stock LS1) to over 700 (stock LS9), and all are the same size, have the same mounting bolt patterns, same exhaust port size and bolt patterns, etc. Put in whatever you can find, "later" just bolt in whatever you want. There are easy to follow instructions available on how to build a 1,000 HP LS series engine.
Whaddya want, how deep is your checkbook?
