I have an '85 and am about 20 minutes away from you.

The quick and simple answer is that you can't do it legally. You can however, make the system work for you.

Taking a bigger motor out of a newer truck can take you a long ways, so long as you transfer over all the smog crap too.

Lets say the you pulled a 5.3 out of an '06 Silverado. You would need all the smog equipment and the original ECU (it has to be a truck ECU otherwise it wont pass). Then you take it to a state ref. who inspects the swap and makes sure that all the parts are working as they should. He'll then give you this cool little sticker that goes in your door jamb and will put a special note on your registration. This little sticker in your door jamb has the information for the motor, what year truck it came from, etc., and when you smog the truck next time, they run the numbers from the sticker instead of the VIN.

Any smog legal mods are fine as well so long as they match the motor. So if you supercharged it, it would have to be a kit for an '06 Silverado and would have to be 50 state legal.

Understand?

Also, you going to the Sacramento Autorama this weekend?
