I guess in '50s NZ if you were going to build a car with a front-mounted V8 engine it would be a single-seater - and there are countless examples of those.
The only front-engined Corvette-powered sportscars I can think of in period were transplants - Johnny Riley's Monza Ferrari, Rod Coppins's Tec-Mec (Ferrari body on Maserati chassis) and the HWM.
Though, as discussed elsewhere on this forum, there were a number of Corvette-engined pre-war coupés...
