I go with Bob Donalds on his general comments. No engine re-work is
worth it's salt without extensive Dynometer testing. One should be able
to produce data from which to construct and display all the performance
parameters. Specific Fuel Consumption, BHp, and myriad of others.  This
would be the only kind of presention about a re-worked or re-engineered
engine that  I would be comfortable with. Performance on the Dyno is the
proof of the pudding.
