I suppose this has been talked about before, but I haven't seen anything.
Anyone thought of doing (or has done) a 5.7, 6.1, or 6.4 swap into a '72-'80 truck (or older)? What about transmission? If you do a '76 or newer, what's the smog laws follow (California, or where ever)? Truck, or motor? Pics?
Just wondering.
