Rbronco1979

I have a 79 Bronco that has been sitting for five years. I made some engine mods so it won't pass smog. I would like to get an engine from a newer Ford truck with fuel-injection. I live in CA and don't know if I can swap for a new engine? Also if I can has eneyone done so with any luck.

Just a few thoughts...

Going for fuel injection is the right idea. I would fit a 94 & up 5.0L on it. The small block should bolt up to the trans (hopefully a three speed auto "C-6"). Those late model years also incorporated mass airflow sensors, making later modifications easier.

The problem you will have is that california isn't just stricter about the amount of pollution, but also tests for a 4th type of exhaust gas that isn't checked in other states (NOx). This is the smog producing gas that they have such problems with in L.A.

Some vehicles had "smog pumps", not sure if that would necessarily fix the problem. For a smog pump, though, you would want to go with an early model F.I. small block (like 87-89). These older models likely have smog pumps and Air injection exhaust manifolds (reduces polution, obsolete by '91).

Check california regulations, see what is necessary. Try to get a California motor that has the right equipment if necessary. remember, you will have to replace alot of electronics for an F.I upgrade
