How familiar are you with CA emissions laws and inspection practices?

I'd guess not very, or you wouldn't be asking.

raiders8498

yeah not that familiar

"Overview

Engine changes continue to present problems and challenges to car owners and technicians. Here are some tips to keep you and your customers on the straight and narrow.

Our recommendation is to rebuild and reinstall the original engine, transmission, and emission control configuration.

When rebuilding an engine, it must be rebuilt to the original equipment specifications. However, if you do decide to change the engine, these guidelines must be observed to ensure that the vehicle will be eligible for smog certification or registration.

Remember, these are guidelines for performing engine changes -- not certification procedures. All exhaust emission controlled vehicles with engine changes must be inspected by an official referee station and must have a Bureau of Automotive Repair (BAR) Vehicle Identification Label affixed to the doorpost.

Remember also, state and federal anti-tampering laws generally prohibit any modification to the vehicle's original emission control system configuration as certified by the manufacturer. And, Section 3362.1 of the California Code of Regulations prohibits any engine change that degrades the effectiveness of a vehicle's emission control system.
California Certification

A federal Environmental Protection Agency (EPA) certified (federal or 49-state) engine cannot be used in a vehicle that was originally certified for California.
Certification Standards

Make sure the engine and emission control configuration on exhaust - controlled vehicles are certified to the year of the vehicle or newer, and to the same or a more stringent new vehicle certification standard.
Classification

Don't mix engine and vehicle classifications which will degrade the emissions certification standards. For example, a heavy-duty engine cannot be installed in a light-duty exhaust-controlled chassis even if they have the same displacement. Non-emissions controlled power plants such as industrial or off-road-use-only engines may not be placed in any exhaust-controlled vehicle.
Computer Controls

If a computer-controlled engine is installed in a non-computerized vehicle, the "CHECK ENGINE" light, the Original Equipment Manufacturer (OEM) diagnostic link, and all sensors, switches, and wiring harnesses needed to make the system fully functional must also be installed.
Emission Control Configuration

Mixing and matching emission control system components could cause problems and is generally not allowed. Engine and emission control systems must be in an engine-chassis configuration certified by the California Air Resources Board (ARB) or U.S. Environmental Protection Agency (EPA). The engine must meet or exceed the requirements for the year and class of vehicle in which it is installed.
Emission Warranty

Voiding the vehicle manufacturer's emission warranty is not allowed.
Engine Modifications

No internal or external engine modifications (cams, pistons, intakes, etc.) may be performed unless the parts are ARB-exempted or EPA-certified for use in the installed engine. Use the database on this site to search for aftermarket parts covered by ARB Executive Orders.
Original Equipment

The installed engine and host chassis must retain all of their original emission control equipment. Diesel-to-gasoline conversions must have all gasoline engine and chassis emission control systems installed (such as fillpipe restrictor, catalytic converter and evaporative emission system).
Smog Inspection

These vehicles must pass a complete smog inspection (visual, functional, and tailpipe)."

my 406 passed smog . Accel SuperRam is smog legal , but Stealth ram is not. Check SoCal board for further assistance

raiders8498

that is all i want to know if its possible without to much trouble

Do you live in Cali? I wouldn't mind getting a 406, maybe for a different car though! I may get another 3rd gen to mess around with.

For the record, technically only a passenger car '88-later 350, LT1, or LS1 will be a legal swap. Anything else is lying to the inspector about what you've got in there.

"Possible without too much trouble" is a very subjective issue. Any motor change is going to be some level of trouble. How much is too much is up to you. The least trouble is making it look like a 305 with CARB certified parts, but again, that's lying. LT1/LS1 is motor change, but totally legal.

Yup I live in California. You can swap out your 305 to 350 327 383 400 without a problem as long as: 1) you do not change the fuel delivery type (carb---> TPI or vise versa and same for tbi engines) 2) pass the sniffer test 3) keep your mouth shut in front of the smog technician regarding your engine or any mods you've done to your baby. Now if you want to swap you fuel system, you got to be very careful (big trouble). If you decided to go this route, let me know

raiders8498

but me car origanarly has tpi and i wanted to get the accel induction is that a good choice or a waist of money, come on i want to know what you guys do to your cars because im not a very mechanical combination person

Are you talking about just the manifold, or the stand-alone DFI system?

Manifold, okay. Stand-alone system, not legal.

raiders8498

the whole system

Won't pass smog.

Just the manifold with your stock system in control will.
