The WS7 was a wonderful engine.
Square bore/stroke; had a real mild bottom, excellent mid and didn't give up on the top; but no it didn't rev to the moon.
Pipe choice is important; you should run one of the RB pipes or a Novarossi 9853.
WS7 wasn't 'excessive' anywhere, but was/is a favored buggy engine for all around use. Mine also gets pretty good mileage...
If you're racing, I'd suggest looking further into your pipe/header and clutch setup.
IF you're bashing...then yeah, ditch and and go buy a 28 or something if that makes you happy.
Make sure the car is geared correctly as well. The prev. owner may have gone up on the clutchbell's tooth count and you need to go back down for your needs probably.
