I've already started working on the body of my 1979 and wouldn't want to sell it and buy a new one at this point. I just want to know which engines are legal to swap?
Can I install a car engine into a truck and still be legal?
I'll be the asshole here and say it:
You are working under the "sunk cost fallacy". Look several people have already said if you want to do a swap go 75 or older. It will be cheaper.
My suggestion fix up the 1979, fix the L20b and BUY a 75 or older 620 to do the swap. IT WILL BE CHEAPER in the the long run.
Or buy a 75 already swapped. For the same money you would spend you could get a VERY NICE truck already swapped and ready to drive...without the time or work involved!
Otherwise you will chase your tail trying to do this total pain in the ass engine swap to CARB standards and spend way more money.
The likelihood is VERY HIGH you will fail and the truck will sit as parts until it goes to the junkyard. We have seen this exact scenario play out several times.
Once again. Do NOT work on engine swapping this truck! Get it running under the L20B or buy a 75 or older and swap it.
Enjoy driving the truck first. Having a vehicle in parts you can't drive for years takes all the fun out and is a very large reason for not finishing the vehicle as circumstances change.
But you probably won't listen and will keep going forward with the engine swap against all advice.... good luck.

Yeh but cars in ca have to be smog every 2 years, so every 2 years, he has to take the ka motor out and install the L20 back, too much work, eh.
He has a '79 620 truck and I suggested an '79 A10 or S10 block and head.... but if you did swap to KA, get a truck KA engine for the swap.
A car L20B block and head wound be indistinguishable from the original 620 L20B which is the intent of the regulations. If you swap the 620 emissions package, carb and distributor. You would have to anyway to remain completely legal.

It's not hard to get a swap to pass the ref. You just need to be thorough in the build process and include anything and everything related to emissions, EVAP, exhaust, etc.
Again, this is why I say it's easier to start with a donor vehicle. It's all laid out there for you to see. With enough pics taken before teardown and plenty of notes and measurements, the build process is actually quite simple.

So I took my Datsun with my mechanic and had him change anything he had to change and fix it right up (He is my uncle, 100% trust this guy). I've decided to restore everything original and slowly upgrade brakes, driveshaft etc....
Engine sounds great. Compression is where it needs to be and has original 90K Miles. I know that after 100,000 it would reset but this one has 90K miles according to the vehicle report!!!

Yes, either him or a shop located next to ours. I own a body shop that is located in SoCal. Its located in an automotive plaza with other shops next to mine (SMOG, Mechanic, Transmissions, Electrical, Sound systems,carwash and all)
I get the hookups!
