Well after doing some research on engines. I found these blueprint engines that are pretty expensive but powerful but you could buy a whole vehicle for the price of just the engine. So they are not cost effective in my opinion. But figure i should mention them. They have some all 50 state legal engines. Here is a reference to CA engine swap rules that are a little confusing in my opinion. Those blueprint engines are race engines in my opinion. Anyway click below and read the rules and As far as mix matching engines its a little vague and confusing.
From what in understand i have to stick to the same model year vehicle for the swap. So for example if i want to do a 2001 ranger i have to have the engine from a 2001 or newer vehicle. I don't think i can go older engine. But you might be able to as long as the engine passes emissions.
So am i correct on that. You can't swap a older engine into a newer vehicle according to the rules in CA.
Or does the age of the engine not matter and it only has to pass emissions for whatever year it is?

I would most likely just do the Explorer/Mountaineer swap Just considering years still mostly...What year ranger and what year explorer would be best. If we had mad money i guess we could use one of those crate engines. But i can't find reference to what vehicles those are for exactly
