Only smog legal LS swap in Ca is the crate Erod kits from GM performance.
Not exactly. The E-Rods are the easiest to get passed, but as long as the engine is the same year or newer as the car it’s going in, and came out of a similar weight class of vehicle, you should be OK. The only issue I possibly see here is that the 5.3 was never offered in a passenger car, except the transverse LS4.

Although the El Camino is kind of a gray area. They might consider it a “truck” in which case he’ll be OK.

Well I'm hoping to get it smogged as an ls1, since everything I'm using is off of one except the block and heads. I didn't think of the possibility that they might check casting numbers on the head though. Will see.

The refs have a fair amount of leeway in approving swaps. Again, your best reference is the “Engine Change Guidelines” link I posted. It’s a little vague in some areas, but it’s the best you’ve got short of a CARB EO number.

Not much today, straightened out my old fuel tank straps and bent them the shape of the ls1 tank

I cut the old fuel tank mounts so the ls1 tank can sit higher

It will be interesting to see the fit of that tank mounted in the car because that thing looks deep.

Please keep us posted, especially if you get it approved! There are a lot of misconceptions about doing engine swaps in CA. This will be very informative to a lot of people. Here's another link I found that might be helpful: http://asktheref.org/
