California legal engine swap

[HRV-LS1]

Need information on an engine swap. Want to put in a 5.3 truck engine into a 95-98 GMC truck. I live in California and I'm not familiar with the smog/installation laws. Can anybody give me any information about this issue? Thanks.

you need to contact a referee station and get the details, the rest is just speculation.

The only real risk you take is if for some reason a cop decides to pop your hood. Most of them don't know what engine belongs in what vehicle tho. The smog guys are usually retards so don't worry about them.

Spoke to the referee and he told me everything needs to be there from the donor vehicle. My question is, how do I know where everything goes (smog parts)? Don't want to put an engine in and find out later that I can't complete the swap because of how the smog parts need to be installed. Does anyone know of what smog parts are installed and where they all go? Is there a certain year that I can look for to do this swap? By the way, I finally got a 95 GMC Sierra and would like to do this swap to it. Thanks.

Move away from the left coast? That would solve all your problems.

There are complete legal swap kits available from gm performance parts. The main thing is the cats and fuel vapor controls for the fuel tank.

I'll try and see what gm performance parts has to offer. Would a 98 tank work with the vapor controls, because I believe the 99 and up are different size and won't fit the 95 GMC.

I believe it can be retrofitted with the tank sensor. It looks like a map sensor that is mounted on the tank to check for leaks in the system to the atmosphere like a loose or leaking gas cap.
