Actually, John, the '78 engine that my customer tried the Kent cam in had
been bored 40 over, had no cat, no air injection, all the new pieces that
accompany a good engine rebuild, and was set up with a 1974 distributor and
a pair of HS4 SUs. The car did still have its rubber bumpers,
though..........
