There is an aftermarket engine made by Historic Racing Miniatures - I got mine through Strada Sports and although mine is the Targo Florio version it is basically the same and can be adapted to all the GT40s
Thanks for all the information guys and fwiw I’ve placed my order for the kit. It’s only going to cost $30 AUS including postage so even if I make a complete hash of things it won’t be that much of a tragedy.
Mark and Martin those models look outstanding, thanks for posting.
Mark what colors (brand) did you use for the blue and the orange/red (wheels) on your kit?
darson i built this model about 4 years ago so my memory is a bit fuzzy. I know the orange was Tamiya acrylic X-6 it was a perfect match for the orang in the decals. The blue was a powder blue in a large spraycan I bought at the hardware store I believe it was Plastic coat brand.
