Brilliant hotrod. Love it. Baltic blue(?) over cream is a tasty combo and nice and cool in the sun.
Much more linear power with TT.
Had the same body on my old 3L, rear fender vents feed a lot of air to the engine room and rear brakes.
Boxed rockers add rigidity to the chassis to cope with the power.

There was another SC converted to turbo that sold earlier this year. IIRC it sold in the $40's on BAT.... nice well done car too.
