73 Duster build named Fred

Any reason not to build the 4" arm stroker? 360 or 340 based, these things will put a smile on your face. My 408 is like a little kid always wanting to go, go, go! The torque is amazing and you can build the upstairs power with cam/heads/intake as you want. Mine doesn't have enough cyl head (Eddie RPM's) to make big power but still manages low 11's.
