Can you put a Late model Fuel Injected Gm Engine such as a LS 6/7 in a 1973 Monte Carlo?

Question

If yes, how big and what are the advantages/disadvantages of carburetor VS Fuel Injection??? If a crate engine comes W/ a carburetor can it be changed to Fuel Injected ????

Answer 1

You can do ANYTHING if you have the time, the money and some mechanical expertise.

You need to ask, is it worth it?

Answer 2

yes you can do it. Fuel injection is more reliable over a carb because it self adjusts and keeps a tune, where a carb needs to be adjusted every once in awhile. Fuel injection is harder to tune versus a carb since it requires a computer.  There r plenty of after market fuel injection systems out to convert a carb to fuel injection.

Answer 3

yes, if you include the Computer, Fuel tank with HP fuel pump, and all the wiring related to it...find a wrecked donor car.

But a Cheaper way is to buy a retrofit kit for it!

Yes, you can, but, the electronics could get complicated. The Monte Carlo could still be ordered from the factory with a 454 until at least 1974, so there are basically no limits on the size of Chevy engine that can go into it. Carb versus E.F.I. is really a matter of preferance. For me, I'd go with the E.F.I. since you're doing all the work to put a modern engine in it, you might as well have a modern induction system to go with it. Also, E.F.I. should give you better driveability and maybe a little better gas mileage (but, we don't care about that do we?). There are many different intake manifolds, as well as complete systems, available from both the GM Performance Parts catalog and the aftermarket that allow you to use fuel injection on crate engines. Some of them are fuel injected already. I would think that the LS 6 and 7 would come that way,possibly with a stand alone computer to simplify engine swaps. I'm not sure about that last part though.

Answer 5

Craig, if you're asking this question then this is way over your head.  If this will be a project car and you want to learn about mechanics then if you have the money go ahead.  I have 36 yrs of Chevy experience and I wouldn't do it.  Good Luck no matter what you decide.

Answer 6

Yes it is pretty straight forward.The best route to take is to get a rear ended donar car.Stick with fuel injection for its better drivability. In order to do this you will need to use a modern transmission that was in the donar car because of the various sensors and compatability issues. It will also at the very least be a 4 speed auto which is better than the 3-speed that would have been oe in your car. If you want a manual trans get a donar car with a manual transmission.You will need the ecm, and I would use th cooling system from the donar car and as much of the engine trans wiring harness as possible.You will also need to modify the Monte Carlo fuel tank and lines for correct fuel return and pressure. There is a lot of work involved, but if done properly will give you a nicely styled car with modern day economy ,emission controls and power.
