I am considering buying a Rebello 2.3 off my friend. It has about 10,000
miles on it. It is a L20b stroked out to a 2.3 with all the tricks, titanium
valves, 44s, street cam, comp header, U60 head. It was dynoed at 185hp with
the torque being around 200. It this going to be a good street motor or is
it too much of a race one?
Thanks
Ryan
