You can run a ls motor with a carb intake and a msd box that runs the coils or efi like most people do.

It is also illegal for a street car. It is illegal to downgrade or disable a engine's low emission package for a street driven car. This law does not apply to a off road car such as a track only car.

Not everywhere. Certainly not here in Iowa. No testing whatsoever.

It is Federal law for all 50 states. Your state simply does not bother to enforce it at this time. Testing is simply enforcement, but laws are only as effective as their level of enforcement. In fact if you swap a newer motor into a older car, the car must meet the emission standards of the year of the newer engine. It is also illegal to swap in a engine that is older than the car.

Welp, then everyone in america is going to jail. Nice knowing y'all.

Are you sure you don't mean california? They've had that law for quite a while, never heard anything about it in any other state.

 

[MrSony]

Haven't found anything in any law in Iowa stating that it is illegal to swap drivetrains into other vehicles. I know california enforces the clean air act that prohibits that notion, but last time I checked I lived in America, not Cali. And if it actually is a law, it's in no way inforced. So it's not really even a law, is it? I've been pulled over more times that I can count, only had a few tickets, and not once did any police give a damn what my engine was. Just that it was too loud, which Iowa does have a law that all vehicles need mufflers (cherry bombs fell off), and cars after 1975 need cats, which my car didn't have but cops didn't care. It might be a Federal Law, sure, for california.

 

[MrSony]

All I've managed to find is this:


And it goes no further than this. Only law even related to the act of vehicle modification engine wise.

 

[MrSony]

I am in no way a legislation expert, just did some googling and showed my findings, or lack thereof. Sorry to hijack the thread lol. Where were we? ah, yes. We're all going to jail and "boo ls swaps".

ENGINE SWITCHING FACT SHEET UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. 20460 March 13, 1991 OFFICE OF AIR AND RADIATION Pursuant to frequent requests for information received by the U.S. Environmental Protection Agency (EPA) regarding the legality and effects of engine switching, this document will summarize federal law and policy pertaining to this matter, and will discuss other related issues. A. Federal Law The federal tampering prohibition is contained in section 203(a)(3) of the Clean Air Act (Act), 42 U.S.C. 7522(a)(3). Section 203(a)(3)(A) of the Act prohibits any person from removing or rendering inoperative any emission control device or element of design installed on or in a motor vehicle or motor vehicle engine prior to its sale and delivery to an ultimate purchaser and prohibits any person from knowingly removing or rendering inoperative any such device or element of design after such sale and delivery, and the causing thereof. The maximum civil penalty for a violation of this section by a manufacturer or dealer is $25,000; for any other person, $2,500. Section 203(a)(3)(B) of the Act prohibits any person from manufacturing or selling, or offering to sell, or installing, any part or component intended for use with, or as part of, any motor vehicle or motor vehicle engine where a principal effect of the part or component is to bypass, defeat, or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine, and where the person knows or should know that such part or component is being offered for sale or is being installed for such use. The maximum civil penalty for a violation of this section is $2,500. EPA received many questions regarding the application of this law to a situation where one engine is removed from a vehicle and another engine is installed in its place. EPA's policy regarding "engine switching" is covered under the provisions of Mobile Source Enforcement Memorandum No. lA (Attachment 1). This policy states that EPA will not consider any modification to a "certified configuration" to be a violation of federal law if there is a reasonable basis for knowing that emissions are not adversely affected. In many cases, proper emission testing according to the Federal Test Procedure would be necessary to make this determination. 2 A "certified configuration" is an engine or engine chassis design which has been "certified" (approved) by EPA prior to the production of vehicles with that design. Generally, the manufacturer submits an application for certification of the designs of each engine or vehicle it proposes to manufacture prior to production. The application includes design requirements for all emission related parts, engine calibrations, and other design parameters for each different type of engine (in heavy-duty vehicles), or engine chassis combination (in light-duty vehicles). EPA then "certifies" each acceptable design for use, in vehicles of the upcoming model year. For light-duty vehicles, installation of a light-duty eng~ne into a different light-duty vehicle by any person would be considered tampering unless the resulting vehicle is identical (with regard to all emission related parts, engine design parameters, and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis, or if there is a reasonable basis for knowing that emissions are not adversely affected as described in Memo 1A. The appropriate source for technical information regarding the certified configuration of a vehicle of a particular model year is the vehicle manufacturer. For heavy-duty vehicles, the resulting vehicle must contain a heavy-duty engine which is identical to a certified configura- tion of a heavy-duty engine of the same model year or newer as the year of the installed engine. Under no circumstances, however, may a heavy-duty engine ever be installed in a light-duty vehicle. The most common engine replacement involves replacing a gasoline engine in a light-duty vehicle with another gasoline engine. Another type of engine switching which commonly occurs, however, involves diesel powered vehicles where the diesel engine is removed and replaced with a gasoline engine. Applying the above policy, such a replacement is legal only if the resulting engine-chassis configuration is equivalent to a certified configuration of the same model year or newer as the chassis. If the vehicle chassis in question has been certified with gasoline, as well as diesel engines(as is common), such a conversion could be done legally. Another situation recently brought to EPA's attention involves the offering for sale of used foreign-built engines. These engines are often not covered by a certified configuration for any vehicle sold in this country. In such a case, there is no way to install such an engine legally. EPA has recently brought enforcement actions against certain parties who have violated the tampering prohibition by performing illegal engine switches. It should be noted that while EPA's policy allows engine switches as long as the resulting vehicle matches exactly to anv certified configuration of the same or newer model year as the chassis, there are some substantial practical limitations to performing such a replacement. Vehicle chassis and engine designs of one vehicle manufacturer are very distinct from those of another, such that it is generally not possible to put an engine into a chassis of a different manufacturer and have it match up to a certified configuration. Therefore, practical considerations will generally limit engine switches to installation of another engine which was certified to be used in that same make and model (or a "twin" of that make and model, e.g., Pontiac Grand Am and Oldsmobile Calais). In addition, converting a vehicle into a different certified configuration is likely to be very difficult, and the cost may prove prohibitive. B. State Laws Many states also have statutes or regulations prohibiting tampering in general. Most of these laws specifically prohibit tampering by individuals. A few specifically prohibit engine switching, using provisions similar to those stated in EPA's policy. To determine the state law in any given state, the state's Attorney General's office should be contacted. In addition, many states have state or local antitampering inspection programs which require a periodic inspection of vehicles in that area, to determine the integrity of emission control systems. Many programs have established policies for vehicles which have been engine switched. While EPA does not require these programs to fail engine switched vehicles which are not in compliance with federal policy, the Agency does strongly recommend that these programs set their requirements so as to be consistent with the federal law. State or local programs which pass illegally engine switched vehicles may mislead federally regulated parties into believing that engine switching is allowed by federal law.

Short version: you can't modify the emissions equipment on a vehicle through engine swapping to a vehicle without any or less equipment. You also can't downgrade or tamper with a engine's low emission configuration. You can only do an engine swap involving a newer engine, and you must include all of the emissions equipment from that newer chassis and no foreign engines that are not somehow certified for use in the US.

Moreover, if you read more of the rules than just the basic swap rule, you'll find rules that also state that if you can prove that the emissions are better, it's allowed. None the less- the intention is to make sure certified packages are kept intact. Basically because it's not realistic to be able to prove that the emissions are equal or better. However, the easiest way to prove that the engine that you put in is cleaner is to use everything from the newer engine. The Federal emissions test is hideously expensive to do, it'd probably be cheaper to just buy a new car which is what everyone wants you to really do!

The car or engine (whichever is newer) has a emission standard that it must meet. If you can't prove it, you can't do it. Aftermarket kits- catalyts, turbos, superchargers, etc- have to meet the same rules. That standard also includes OBD (depending on the year) and evaporative emissions. BTW, LS OBD enhanced Evap systems will not work with older non enhanced gas tanks like those found in G bodies, rendering all LS swaps except for the Erods crates, illegal in older cars. It works the other way too, every LS swapped older vehicle must have all the stock parts (gauge cluster, cats, stock enhanced evap stuff, everything) from the year vehicle the LS came out of.There are a lot more complex rules regarding newer engines and cars, newer the year the more strict the laws are.

Well I'll be. To reiterate, we're all going to jail. Thanks for clarifying. And I'm still glad I don't live in california.
