Can you put a stright 6 in your 1977 el camino and get rid of the 350 v8 gas pig?

Yes, you can replace the 350 V8 in a 1977 El Camino with a straight-six engine. This swap can improve fuel efficiency since straight-sixes generally consume less gas than V8s. However, it will require modifications to the engine mounts, transmission, and possibly the wiring and exhaust systems. Be sure to check compatibility and performance expectations before proceeding with the swap.
