Kt's are great we had a couple in OZ small block with 2 drive ssm
Merc also had a package back then a KT 475hp Typhoon, was used in ski race boats but was suited to KT's

In the unlimited races in OZ on short tracks the KT's would race the unlimited hydro's a real David and Goliath stuff, hydros doing wide fast turns and the KT like an F1 tunnel boat on the corners.
They need capsules though
