A V8engine is not a bad motor, but its gasoline consumption makes it prohibitive, specially if modified.
My 610 is getting a 5 speed gear box ( to replace the stock automatic ) . The engine was in perfect shape, so I am adding a 38DGES Weber ( later on I will add twin DCOEs) headers, and a cam.
That should make a fun to drive fast and reliable Datsun.
If I had to choose from 2 engines sitting on the floor, both in the same stage , I would go for the L20B, because it has more torque , in city driving, that torque feels great. If you have an L18 already, in that case, just keep it, modify it to suit your driving preferences, and enjoy it.
L18s rev higher , that is the plus, but unless I was looking for a high RPM race car, I take torque over RPM, specially when talking about two similar engines, RPM being not a dramatic difference.
